Tires
In discussions of supple tires, you sometimes hear comments along the lines of: "If wide tires are so great, why don't they score at the very top in lab tests?" That's a good question, and it goes to the root of how to test things: If tests don't replicate...
When I was preparing my FKT ride over the notoriously rough gravel of the Oregon Outback last year, I needed to figure out what tire pressure to run. I looked at some online tire pressure calculators. One suggested to run my 54 mm-wide tires at 16 psi (1.1 bar) –...
Before there was gravel, there was Paris-Roubaix. The famous race used to be a relic from a past when many races of northern Europe went over cobblestones. While other races – especially the Tour de France – became 'sanitized,' the Queen of the Classics played up its image as the...
When we asked Lael Wilcox which tires she needed for bikepacking, the Fleecer and Oracle Ridge dual-purpose knobbies were the result: great traction on loose and muddy surfaces (and snow), but fast and grippy on pavement. Plus quiet thanks to our noise cancellation technology. These tires cover the multitude of...
We just received another tire shipment, this one mostly with Extralight models that had been out of stock for a while. For me, the Extralight casing is one of the things that defines our Rene Herse tires. It's the most supple casing you'll find anywhere, matched only by the finest...
Let's start with the new tire: We're excited to expand our 26" offerings with the 26" x 1.8" Naches Pass Endurance. The Naches Pass is the 26" equivalent of our iconic 650B Babyshoe Pass – the tires we ride on our own bikes more than any others. In fact, Natsuko runs...
Our tires are developed in the field, by some of the world's best riders. For us, racing isn't about marketing, but about testing and improving our products. And there's probably no test as harsh as the Silk Road Mountain Race: A 1858 km (1154 mile) trek over old Soviet military...
The response to the new 650B x 55 mm Umtanum Ridge surprised everybody: The Endurance casing was sold out within 4 hours, and the Extralights lasted only a little less than a day. We just received another shipment, so both models are back in stock. The Standard casing will follow...
The new 650B x 55 mm Umtanum Ridge tires have landed! Now our widest knobbies are available in the three most popular wheel sizes: The award-winning 700C/29" Fleecer Ridge is perfect for the latest drop-bar mountain bikes. The 26" Humptulips Ridge has made classic mountain bikes fun again. And now...
With the 2021 Tour Divide happening this year – on a shortened course, since the Canadian border is still closed – Neil Beltchenko from bikepacking.com looked at what he considers the best tire for this challenging 2,745-mile (4,418 km) course. Neil has more experience than most: He has ridden and raced...
All our research shows that wide tires roll as fast or faster than narrow tires (if they use the same casing). How come that generations of cyclists believed that narrow tires are faster? The answer is simple: Narrow tires feel faster. They simulate the sensation of higher speed – without...
Last week, we talked about how real-road tire tests have revolutionized our understanding of how bicycles work. We've looked at different ways of testing tires, and why it's so important to perform tests carefully and under realistic conditions. Today, let's look at some results of our testing. Are Wider Tires Slower?...
Ever since we've worked with Lael Wilcox to develop the 29" / 700C Fleecer Ridge dual-purpose knobbies, we've been deluged with requests for 26" and 650B versions with the same noise-cancelling tread pattern. We launched the 26" Humptulips Ridge late last year. Now we're excited to announce the 650B /...
One of the secrets behind the performance of Rene Herse tires lies in our R&D. We run our tests under real-world conditions, so we can optimize our tires for what matters: riding on real roads. When we started our research 15 years ago, high-performance tires were narrow and designed for...
We're excited that our Fleecer Ridge tires won the 2021 Design & Innovation Award in the Category Off-Road Components. This prestigious European prize is based on real-world testing. The 30-strong, international jury consists of journalists, test riders and engineers who are amongst the most renowned experts in their respective fields....
The new Humptulips Ridge 26" x 2.3" knobbies have arrived! Usually, we airship just a few tires for photography, but with so many riders eagerly awaiting these tires, we sent over a few more. We have a small quantity with Standard and Extralight casings (tan sidewalls), as well as the...
We usually don't expect to get 'Gear of the Year' awards – we don't advertise, since we prefer to spend our resources on R&D and high-end materials rather than marketing. And our products are expensive to make, so we can't send out a lot of review samples, either. We're especially...
It's been a long time coming – the latest of our dual-purpose knobbies, the Humptulips Ridge 26" x 2.3", is in production now. The tires renew our commitment to the 26" wheel size, whether it's for modern all-road bikes like my Firefly or classic mountain bikes that can be a...
It's all nice and well when we talk about our tires – why we design and manufacture them a certain way, how we think they perform, etc. The real proof is when others test them. Especially independent testers who've ridden dozens or hundreds of tires. And if the review comes...
In France, the Tour is one of the rituals of summer. I can't count how many times during my research I've interviewed somebody while the colorful images were playing on TV in the background. Racers, randonneurs, cyclotourists – all enjoy the grand landscapes, the beautiful form of the riders, the drama...
1,409 miles and more than 115,000 feet of climbing. The French Divide is a bikepacking race that traverses the entire length of France from North to South. (more…)
Lael Wilcox has been enjoying her Oracle Ridge prototypes all summer in Alaska. Now you can get a set for your bike, too. The new tires are now in stock with Standard, Extralight and Endurance casings. (more…)
When we introduced the our Fleecer Ridge 700C x 55 mm dual-purpose knobbies, we sent two sets to Neil and Logan at Bikepacking.com. Since the Fleecers are our first tires specifically intended for bikepacking and the Tour Divide, we were eager to get their feedback. That was a few months...
When bikepacking legend Lael Wilcox talked about the tires she wanted for her bikepacking adventures, she mentioned a 48 mm-wide knobby in addition to the Fleecer Ridge 700C x 55: Ideal for many modern gravel bikes like her Specialized Diverge. Lael suggested a great name for the new tire: One...
There's a lot of talk about optimizing tire pressure these days. In years past, most of us inflated our tires to the maximum pressure rating shown on the tire sidewall. It's more complex now. Like Goldilocks, we add air and then let out some again, until we've found what seems...
These days, it's widely accepted that 700C wheels roll faster than smaller hoops. It's a bit like the old belief that narrower tires are more efficient – so self-evident that it doesn't even need explaining. After all, simple physics tells you: A bigger wheel rolls faster, because it hits bumps...
Selecting Rene Herse tires for your bike is easy, because our program is logical and simple. It's all based on performance. We started making tires because we wanted to ride high-performance tires on the gravel roads of the Cascade Mountains. We came from a decade of racing on hand-made tubulars...
Car and motorcycle tires have been tubeless for decades, but bicycle tires have continued to use tubes. That changed during the 2010s, when first mountain bikers and then the riders of all-road and gravel bikes started to experiment with tubeless technology. They reason was simple: If you could run your...
With all the emphasis on gravel and less-than-smooth backroads, it's easy to forget the joys of pure speed as you glide over smooth pavement. And perhaps nothing is more about speed than triathlons. Few people know that both BQ team rider Mark and I did triathlons way back in the...
https://youtu.be/IOscnup4Rys If you missed yesterday's live talk on Bikepacking.com, it's now uploaded to their channel – click above to view it. It was a fun conversation with two Tour Divide racers, Lael Wilcox and moderator Neil Beltchenko, about what they want in a tire, how we're developing tires, and how we've...
We've got the new Fleecer Ridge 700C x 55 bikepacking/gravel/all-round tires in stock now. They come in the Standard, Extralight, Endurance and Endurance Plus casings. This means you can get the volume and groundbreaking tread pattern – more of that in a moment – with a full range of casings....
We're expanding our tire line-up for tough conditions: Two of our most popular tires are now available in reinforced Endurance and Endurance Plus versions. (more…)
When we developed our first knobby tires, we wanted tires that could handle all conditions, not just mud and snow. We wanted tires that rolled fast on the road, yet offered tenacious grip when conditions got really tough. We wanted a tire for adventures where we don't know what lies...
Long distance bikepacking is all about making equipment compromises. Generally speaking, for me, bikepacking is multi-day dirt-road riding and carrying what I need along the way. Road surfaces, conditions, and weather are ever-changing— that’s part of the adventure. When setting out for a tour, I select equipment based on what...
Even in these troubled times, most of us continue to ride our bikes, at least here in North America. We've been encouraged that even during the 'shelter-in-place' in the San Francisco Bay Area, solo bike rides continue to be permitted. Over the last year, we've worked on re-introducing FMB tubulars to...
Many of you asked for more tires with Endurance casings... The 700C x 35 has long been a favorite of gravel racers and all-road riders. Now you can choose between the versatile Standard casing, the superfast Extralight and the tough (but still lightning-fast) Endurance. (more…)
Editor's Note: 'Gravel' means different things in different regions, from the smooth dirt roads of Vermont to the Flint Hills of Kansas. Few riders have as much experience riding and racing all over the world as Ted King. Here is how the 'King of Gravel' chooses his tires. It’s only in the...
Rene Herse tires are safe to use on hookless rims from Enve and Zipp – even when mounted tubeless (for tubeless-compatible tires). Over the last year, we've worked with the engineers from both companies to ensure the full compatibility of our tires with their rims. Tubeless tires are an emerging technology....
When we started this series to celebrate Bicycle Quarterly's 15th anniversary, we thought we'd eventually run out of myths. But it seems that new ones are created as fast as we can debunk old ones. The latest is "700C wheels roll faster than 650B." This is stated with the same certitude...
The euphoria about gravel bikes is hitting a snag: Many riders feel that their gravel bikes are slower than their road bikes. For example, James Huang, the technical expert from CyclingTips.com, posted: "I've been spending too much time on gravel and mountain bikes lately. Good to be reminded what real speed...
You asked for it... Many customers requested our Barlow Pass with the Endurance casing. It makes sense – 700C x 38 is a versatile size. If your rides are littered with glass, steel wires or goatheads, the Endurance casing is going to be your friend. You get a tire with...
Rene Herse tires are available in many widths, with two tread patterns and four casings. All this so you can find tires that are ideally suited to how and where you ride. Today, let's look at the different casings. Which is best for you? (more…)
We like Road.cc, the British web site, because they really ride the products they test. They've got a number of testers, and their opinions are refreshingly unbiased and honest. At the end of each test, they ask their reviewers "Would you buy this product?" and "Would you recommend this product to...
Autumn means colder temperatures and rainy weather, here in the Cascade Mountains and in many parts of the world. More than ever, the grip of our tires is on our minds. Why do all Rene Herse tires have black tread? Colorful treads can look nice, but black rubber offers the...
How fast are our tires? We know that the casing, and not the width, determines a tire's speed. When I rode Paris-Brest-Paris on 42 mm-wide tires (above), I knew that I wasn't giving up any speed over narrower rubber. But in absolute terms, how fast are our Rene Herse tires? Manufacturers'...
Tubeless tires have changed what we can do on a bike. When the terrain is really rough, not having to worry about pinch flats allows us to run lower tire pressure for more comfort, more traction and more speed. (The speed comes from the lower pressure on rough surfaces, not...
We developed the Endurance casings for our Rene Herse tires based on requests from gravel racers like Ted King (above), who need tires for truly harsh conditions. A race like Dirty Kanza traverses 200 miles of sharp stones in the Flint Hills of Kansas. The lead racers travel at high...
Our series of 'Myths in Cycling' continues with a look at rim width. You often hear that wider tires should run on wider rims. Intuitively, that seems to make sense – match the wider tire to a wider rim. You also hear that wider rims make the tire handle more...
With wide tires, you can tune the ride of your bike to the terrain and to your personal preferences. This gives you options that simply did not exist in the past. Gone are the days when we inflated our narrow tires to the maximum pressure and rode on rock-hard rubber. Even...
It's hard to believe that the first Oregon Outback, that incredible 363-mile gravel race, was just five years ago. It's almost like we live in a different world now, so much has changed... Back then, the idea of running a race that traversed the entire state of Oregon from south to north...
Working with Ted King, winner of last year's Dirty Kanza gravel race, has added a new perspective to our R&D. We've got a lot of experience riding gravel, even racing it, but today's mass-start races aren't the same as exploring the Cascade Mountains on forest roads, or even racing the...
Like many cyclists, we love climbs, but we live for twisty downhills. The feeling of the bike leaning deep into a turn is something that is hard to explain, yet easy to enjoy. https://youtu.be/mvGv9IEiDzY This video clip was taken on a short descent toward Lake Washington. We know this road well, and...
When Ted King recently won the Epic 150 gravel race in Missouri on our Rene Herse Steilacoom tires, many were surprised that he ran knobbies on a fast course. But there were a few muddy corners where the knobs would provide valuable grip, and Ted knew that on the smooth...
As part of our series on myths in cycling, let's look at wheel size and how it affects speed. Even though all-road tires have grown wider in recent years, many bike makers have stuck with 700C wheels. It's a size that is familiar to road cyclists, and there is also...
[youtube https://www.youtube.com/watch?v=zmt02COlmb4?rel=0&w=640&h=360] The Juniper Ridge 650B x 48 mm dual-purpose knobbies have arrived. Unlike any other all-road tire, they combine excellent speed and cornering grip on pavement with unrivaled traction in mud and snow. At 450 g (Extralight) and 510 g (Standard), they are among the lightest tires in this popular...
They call Ted King the 'King of Gravel': Winner of both the Dirty Kanza and Grinduro in 2018, he's the man to beat. With 'gravel' being the fastest-growing segment of the bicycle market, even professional teams are lining up to challenge Ted. So what does a champion do when others...
Tubeless tires have eliminated the risk of pinch flats. For riding in really rough terrain, they are a game changer. But like all new technologies, it's taken some trial-and-error until we figured out how to run bicycle tires tubeless. Of course, tubeless tires are nothing new. Car tires have been tubeless...
All-road bikes with wide tires are the hottest trend in cycling. There is a level of excitement that we haven't seen since the mountain bike boom of the late 1980s: These new bikes bring new people into the sport, who are enticed by the idea of cycling on small roads,...
"An exceptional tyre that will make you faster and happier." That was the verdict when the British web site www.road.cc tested our Bon Jon Pass tires recently. When we hear positive feedback, whether it's from a professional tester or a customer, it makes our day. I smiled when I read the calculation...
This used to be one of the first things you learned as a cyclist: If you want to go fast, make sure your tires are pumped up to the maximum pressure. The harder your tires are inflated, the faster they roll. We now know that this is not true. The realization...
Winter riding is fun. The crisp air, the clear skies and the beautiful views. Getting out and breathing fresh air. There are many reasons to enjoy it. Winter riding requires preparation. The most obvious is clothing – which we'll leave for another post. Today, let's talk about what makes a good...
One of the benefits of wide tires is that they run at lower pressures. Yet the supple casings of our Rene Herse tires require higher pressure to corner well and not bottom out on big bumps. Doesn't the higher pressure negate the benefits of wider tires? Think of the tire casing...
We are excited about a number of new products. MKS has reworked their popular Sylvan pedals with silky smooth cartridge bearings. Now called the Sylvan Next, we've carried the Touring version for a while. New in the program is the Track pedal (above). The new Track pedals are a great choice...
Our ideas of what is a performance bike have changed a lot in recent years! The most exciting bikes of the moment are bikes like the Open U.P. – a carbon race bike that accepts 50 mm-wide tires! Not too long ago, every performance road bike had 700C x 23 mm...
Road.cc tested another Compass tire. After the Barlow Pass and the Steilacoom dual-purpose knobbies, they had a go with the Switchback Hill 650B x 48 Extralights. This time, they used a different tester, Dave Atkinson. He liked the tires just as much... His conclusion echoes ours: "At a time when people...
High-performance bicycles have changed tremendously in recent years. As one manufacturer said at last year's Interbike: "In the past, everybody asked how much your bike weighed. Now all they want to know is how wide a tire it fits." Wide tires have revolutionized how we view performance bikes. In the past,...
At Compass, we see little point in replicating what you already can buy from others. When we made our first knobby tires, we wanted true dual-purpose tires. Could the new knobbies match the on-pavement of good road tires, yet grip as well in mud as true cyclocross tires. Impossible? You'll...
To celebrate Bicycle Quarterly‘s 15th anniversary, we are looking at myths in cycling: things we used to believe, but which we’ve since found out not to be true. Today, we explain why your bike's weight distribution does not directly translate into your tire pressures. (more…)
We are proud to introduce our biggest tire yet, the much-anticipated 700C x 55 mm Antelope Hill. The new tires have arrived with the latest shipment and are now in stock. Antelope Hill is the unofficial name of the last great climb of the iconic Oregon Outback, the 360-mile gravel race that...
In the 15 years of Bicycle Quarterly, one of our discoveries has been that testing bicycle performance isn't easy, and that taking shortcuts often has led to erroneous conclusions. Carefully designed tests that replicate what happens when real cyclists ride on real roads have allowed Bicycle Quarterly to debunk several myths. Certainly,...
When tubeless tires first became available, they were designed for mountain bikes, and it was their resistance to pinch flats (above) that made them popular. Off-road, there are few nails or broken bottles that can cause punctures (and even those usually will be pushed into the soft ground rather than...
To celebrate 15 years of Bicycle Quarterly, we are examining myths in cycling – things that we (and most others) used to believe, but which we have found to be not true. Today, let's look at tire tread: Tread patterns matter – they can make a difference – even on the...
Recently, the German magazine TOUR published a table showing the 'five fastest tires in the world.' We are excited to see our Rene Herse Bon Jon Pass 700C x 35 mm tires (back then still under the Compass label) on this list, in the company of the fastest racing tires....
When we started to publish Bicycle Quarterly 15 years ago, it seemed that most of the technical aspects of bicycles were well-known. And yet, as we tested many different bikes, we started to question many of the things we had accepted as 'facts.' To celebrate our 15th anniversary, we’ll look...
The updated Compass Babyshoe Pass TC 650B x 42 mm tires are now in stock in all models. What's new? We took our most popular 650B tire, and made it tubeless compatible. When you are riding fast on rough gravel, tubeless really makes sense – as I found out when...
Last weekend was the first cyclocross race in Seattle. Almost every year, the first race catches me by surprise. Summer is over? It's 'cross season already? Usually, I oil the chain on my trusty Alan 'cross bike and head to the races. This year, the Alan's tubular tires needed regluing. The...
Many cyclists dream of a dual-purpose tire that rolls smoothly on paved roads, but has knobs that dig into the surface when it gets slippery. In the past, combining these two qualities in a single tire has been elusive. Usually, the knobs were too squirmy for good performance on pavement...
If there is such a thing, Babyshoe Pass is our favorite tire here at Compass and Bicycle Quarterly. It's 42 mm width gives it great cornering grip, comfort and puncture resistance. The 650B wheel size offers nimble handling with wide tires. The Babyshoe Pass is named after an iconic gravel...
Long-time Bicycle Quarterly reader Matt Surch (above) put his name on the map when he won last year's Steaming Nostril gravel race on Compass Bon Jon Pass tires. We checked back in with him to see how the tires performed in the year since then, and to hear about his road racing...
We've experienced a profound revolution in road bikes in recent years: It used to be that to go fast, you rode narrow tires and pumped them up to the maximum pressure. If you wanted more comfort, you used wider tires and (maybe) lower pressures, but you knew that you'd be...
The long days of summer see us heading far into the mountains. Often, our ambitious plans push the limits of even the longest days... Above, Natsuko descends the incredible chain of passes in the Cevennes mountains of France. This amazing tour is featured in the latest Bicycle Quarterly. Just in time...
It's always interesting when bike industry people talk among each other, off-the-record. On the ride from the airport to Paul Camp a few weeks ago, one bike tester was still visibly shaken when he related: "My tubeless tire blew off the rim yesterday. I almost crashed." Worried that this might have been...
First, I want to apologize that several Compass tire models are out of stock. Orders from our distributors in Europe and Japan have exceeded our expectations, and tire production has to be scheduled long in advance... The tires now are on a boat to Seattle. We should have all models back in...
At Compass Cycles, we love riding on gravel roads, so it may come as a surprise that we don't make "gravel" tires. Compass tires are road tires, perfected for use on paved roads. The rubber compound is optimized for grip on pavement, and the "chevron" tread pattern interlocks further with the road...
We thoroughly test every Compass product before we release it. We also seek unbiased evaluations from experienced riders who weren't involved in the development of the products. For the new Compass Steilacoom cyclocross tires, we gave them to a number of cyclocross and gravel racers. Two of them have reported...
Compass Cycles is introducing two new models to its tire line. We've had many requests for 700C and 26" versions of our iconic 650B Babyshoe Pass tires. Here they are! We've added 2 mm to the width, because we found that 44 mm-wide tires will fit most bikes designed for wide 700C and...
Congratulations to Andreas Behrens of LaFraise Cycles for completing the amazing Transcontinental Race. Riding unsupported for almost 2,400 miles (3900 km) over a course that traversed all of Europe, Andreas completed the non-stop race in 15 days and 12 hours. The course traversed the highest mountain ranges of Europe – above the view...
Over the last few years, the idea that higher pressures don't make your bike faster finally has become accepted. Many cyclists now run lower pressures to improve comfort and traction, without giving up anything in speed. On gravel, lower pressures actually make you faster, since the bike bounces less. On soft...
"Buy the nicest, most supple tires you can afford; and buy them in the widest width that you can fit in your frame." That is Joshua Poertner's summary of a panel discussion on Cyclingtips.com. Joshua used to be the president of Zipp, the makers of super-fast aero wheels, and he did a lot of...
How does it work that wide tires are as fast as narrow ones? It is really simple: Comfort = Speed When your bike vibrates, energy is dissipated as friction. That energy must come from somewhere – it no longer is available to propel the bike forward, so your bike slows down. That is why your...
This is just a quick note that our popular 26" x 2.3" Rat Trap Pass tires are back in stock in all versions. We've been surprised by the popularity of these tires... Many cyclists have a cherished old mountain bike, an expedition tourer or a tandem that is transformed with a...
When the Australian Matt Hayman won the European Paris-Roubaix race yesterday, it came as a huge surprise to everybody, including Hayman himself. However, nobody was surprised that Hayman rode on super-supple tires. With their tan sidewalls, Hayman's tires looked like FMBs or Dugasts, but first reports insist that they actually were made...
What is the 'correct' tire pressure for your bike? The simple answer is: Whatever feels right to you. Confused? Here is how it works: In the past, many riders inflated their tires to the maximum pressure rating. Now most cyclists now recognize that the optimum pressure often is much lower. But what is the right tire...
Recently, I posted about slick tires and why they tend to offer poor traction, especially in the wet. Almost predictably, some Internet "experts" declared that it was all wrong. One of the more polite comments was: "Wow, lots of misinformation in this article." I guess it's normal: If your research is breaking new ground,...
During the R&D of the Compass tires, I was surprised how much difference tire treads can make. I rode three sets of tires with the same casing, same tread rubber and same width, but different tread patterns: standard Grand Bois Hetres with large longitudinal ribs throughout the tire tread "shaved" Hetres where...
In our last post, readers noticed the image above and asked about cornering. How am I able to lean the bike so far? Wider bicycle tires corner better than narrower ones. This may run counter to what many cyclists believe, but it's easy to explain. The reason is the lower pressure...
This year's PBP saw a significant number of riders on Compass tires. Of course, we (Jan, Theo, Hahn) rode them, too, but it's always nice to hear from others how our products are doing. J. O. from Vancouver, B.C., and his wife rode a tandem. We gave them our samples of the...
Update 08/2022: This post was written in 2015, when the first tubeless Compass/Rene Herse tires were introduced. Please check this post for more up-to-date information on Rene Herse tires and tubeless. I was trying to put a photo of the new Compass tires' bead here, but it's hard to photograph the...
We recently received the first production samples of the new Compass tires. We've been testing the high-volume tires on our own bikes, but we don't have any bikes designed for the 26" x 1.25" Elk Pass tires. Fortunately, a Japanese friend was visiting, and she took the new Elk Pass Extralight...
Inner tubes often seem like generic commodities. One is as good as the next – so buy the cheapest one... I used to think that, too, until I started to see split seams, valves separating from the tube, and other mysterious flats that were not caused by "outside influences". Around...
