During the last week, Bicycle Quarterly and Compass Cycles have been mentioned in several news stories. The popular web site www.bikepacking.com featured an article about converting a 700C bike to 650B. They wrote: “The benefits are fairly obvious. Wider tires offer more floatation, a more supple ride, and are all around better suited to dirt and gravel surfaces. They can also be just as fast as road tires.”
They equipped their bike with Compass Switchback Hill 650B x 48 mm tires, and we talked about some of the things to consider in these conversions: clearances, bottom bracket height, gearing, etc. The article is a great introduction if you’ve looking into running 650B wheels on your disc-brake bike.
It’s not every day that you get a call from Matt Wiebe, the editor of Bicycle Retailer and Industry News: “We’re working on a cover story about big car tire brands like Pirelli and Goodyear entering the bicycle tire market. We’d like to talk to Compass as one of the established smaller brands in the high-end tire market.”
In the article, Wiebe explains how Goodyear is proud to offer 100 SKUs (Stock Keeping Units), while Pirelli plans to expand into gravel tires, quoting their head of sales: “Gravel is growing in Europe, and I think it will quickly be a big part of the road market.”
Matt Wiebe contrasts this with Compass, explaining how our program “grew out of the tires we needed to do the type of riding we liked — long rides in the mountains on road and dirt surfaces.” The article shows how the industry is trying to catch up with the trend toward high-performance tires – a trend that caught them by surprise because it originated with riders and not with the industry.
Global Cycling Network has brought the latest research about tires into the mainstream. In a recent segment, they looked at why you need lower pressures to make wider tires perform better. They talk about suspension losses – crediting Bicycle Quarterly (Thank you!) – and test different tire pressures on cobbles. No surprise: When the going gets really rough, the lowest pressures roll fastest.
Earlier, GCN took three bikes to the same cobbles: a racing, a cyclocross and a mountain bike (below).
Again, readers of BQ and of this blog will not be surprised: The bike with the widest tires was fastest. In GCN‘s test, it was the mountain bike, even though the data showed a lower power output when the riders were on the mountain bike. The explanation is simple: The lower suspension losses more than made up for the mtb’s wider Q factor, lack of ‘planing,’ etc., that limited the tester’s power output.
Now imagine if GCN had tested a true allroad bike instead of the mountain bike! A bike like my Firefly (above), which enables the rider to put out the same power as on their racing bike and which has tires as wide as their mountain bike, plus its more supple tires reduce rolling resistance and suspension losses even further. From our own on-the-road experiences, we know that it would easily outperform the mountain bike. Perhaps we’ll see that test in a future episode – for now, GCN already is pushing the limits of what a mainstream cycling audience finds believable…
With all this exposure, it’s nice to see that many of the ideas we’ve championed over the last 15 years are getting widely accepted. Click on the images above to read the full stories!
