12-Speed Rene Herse Cranks

We're excited to announce that our ramped-and-pinned chainrings are 12-speed compatible. We knew that 12-speed was coming when we developed our 11-speed rings, so we tried to anticipate the requirements, so that our chainrings would be compatible with 12-speed as well. Now we've completed our testing, and we're happy to...

48/33 Rings for Rene Herse Cranks

We're offering a new chainring combination for our 11-speed compatible Rene Herse cranks. The 48/33 is a perfect size for fast-paced group rides – you won't get dropped even on downhills with a tailwind, yet the 48 is a bit smaller than the more common 50, allowing you to...

Longer cranks should be stronger

Our Rene Herse cranks are available in three length: 165, 171 and 177 mm. We chose 3.5% increments, because that is the smallest difference you'll notice as you ride. That part is just common sense. What makes our cranks unique among small-production cranks is that we use different forging dies...

René Herse: The Beauty of Function

At Compass Cycles, we have taken much of our inspiration from René Herse and his legendary bikes. In the past, we've talked about the great performance and incredible reliability of Herse's bikes, but what is even more striking is their beauty. You notice it immediately when you look at...

Compass 11-speed Chainrings

Compass Cycles is introducing the first-ever 11-speed-compatible René Herse cranks and chainrings. And the first-ever René Herse chainrings with ramps and pins. These are not just any ramps and pins: They're carefully engineered to shift as well as the best cranks from the big manufacturers. We are proud to offer...

Why René Herse Cranks Aren't Anodized

Sometimes, we get questions about why our René Herse cranks aren't anodized. Some even wondered if this was a cost-saving measure. Rest assured, Compass never will choose a cheaper process over a better one. There is a reason why our cranks aren’t anodized: When I was racing, I bought a beautiful used...

Choosing Your Crank Length

Our Compass René Herse cranks are available in three lengths to cover the needs of nearly all cyclists. The lengths we offer are a bit unusual, but there is a reason for this: Our cranks use dedicated forgings for each length. The "net shape forging" makes our cranks stronger than...

René Herse Cranks: 177 and 165 mm

The photo above shows raw forgings for Compass René Herse cranks. Perhaps you will have spotted that they are all different: Their length varies in 6 mm steps. We introduce René Herse cranks now available in 165 mm and 177 mm lengths, in addition to the 171 mm we...

Why Do We Make Custom Chainring Bolts?

Recently, we received our custom René Herse chainring bolts (above). Why in the world would we go through so much trouble and expense to make custom chainring bolts? They are pretty significant little bolts, because they are the finishing touch on the René Herse cranks. René Herse chainrings are 1 mm...

Small Differences Can Matter

Recently, I was on a familiar road, but riding it did not feel familiar. It seemed like I was straining to stay on top of my gear, whereas usually I just spin along. Was I exceptionally tired? I didn't feel that way... Then I remembered that I had replaced my...

Supporting the Classics

When we became custodians of the René Herse name, we had three goals in mind: Bring back some of the best designs of René Herse, so that today's cyclists could enjoy their excellent function and aesthetic. Support classic René Herse bikes with components, so that they can be kept on the...

Meet Our Polisher

Eric Hayes is the craftsman who polishes our René Herse cranks, locally on the outskirts of Seattle. These days, most bike parts are black, and few in the bike industry still have the skills to polish metal without grinding off too much material, which looks ugly and affects the...

Crank Bolt Wrench

Our René Herse cranks come with classic 15 mm crank bolts. They are beautiful and easy to tighten. However, it can be hard to find a matching 15 mm wrench. Most wrenches have walls that are too thick to fit inside the hole of the crankarm. (We cannot make...

Trouble with STI Triples

Triple cranks are a good choice for some riders. The most common shifting system for triple cranks, Shimano's STI, only works with Shimano chainrings. Unfortunately, Shimano's chainring combinations are of limited use to most riders. If you want to customize your chainring sizes, you will have to use downtube...

Passing the Test

When we designed the new René Herse cranks, our goal was to create a crank that was as reliable and safe as any on the market. After all, we ride these cranks ourselves. We are especially proud that these cranks pass the stringent EN standards for racing bikes (EN...

Will I be able to get chainrings?

Question from a potential customer: "If I purchase a Rene Herse crankset with its non-standard bolt-circle diameter, what guarantee do I have that Compass Bicycles will continue production of the chainrings for 5, 10 or 15 years?" Compass Bicycles makes products that we expect to last for decades. We have...

100% Quality Control

Some customers of our René Herse cranks have noticed that their brand-new cranks show traces of having been mounted on a bottom bracket. Did they receive used cranks by accident? No, the cranks are brand-new. As part of our quality control, we mount each crank, with the chainrings the customer...

René Herse Cranks

Compass Bicycles and René Herse Bicycles are proud to introduce a modern version of the classic René Herse crank. The new crank will be available this fall. Some products are hard to improve; they make you wonder why all components are not made that way. The classic René Herse cranks...
