Rene Herse Cycles

32” wheels are the next big thing, we’re told. The reaction has been mixed: Some are excited about the idea of going faster. Others don’t want (or need) a new bike. What’s been missing is science: Are bigger wheels really faster?

In the RH Journal, we discuss why ‘roll-over’ isn’t a factor on pavement and gravel: Bicycle wheels aren’t rigid, but our tires contain air. They absorb irregularities within the tire—without needing to lift bike and rider.

What about the added momentum of bigger wheels? Find out why the slower rotation of the larger wheels cancels out their extra momentum.

The full story includes the theory (physics) AND real-world measurements. Head to

Crowdfunding deadline for all-black Rene Herse tires has been extended until end-of-day May 4, 2026. If you’re hankering some of our most popular models with all-black Endurance casings (plus a new Extralight), now’s your chance!

A 2-hour window between rain and thunderstorms—perfect for a quick ride over to the Eastside and back.

Returning from a night-time spin just before the rain starts somehow feels like you got a freebie!

TBT to 10 years ago when we climbed above 4,000 m on the flanks of the big volcanos of Mexico—all part of a proof-of-concept of ultra-wide all-road tires. Back then, ‘gravel grinders’ were still unsure whether 32 or 35 mm rubber would be faster on rough gravel. Fun memories that changed the cycling world!

After years of R&D and half a dozen patents, Rene Herse is excited to present revolutionary safety aids that take much of the danger out of cycling.

From anti-lock brakes to stability control, plus anti-wheelie and a brake assist that uses radar to detect if a rider in a paceline is about to brake, the new system integrates new technologies to make cycling safer than ever before.

The start of the wide-tire revolution: 10 years ago, we took the first gravel bikes built for truly wide tires (>50 mm) onto an incredible adventure. More than just an epic ride, it was a proof-of-concept.

After traversing the 12,200-foot Paso de Cortes in Mexico, it was clear that ultra-wide tires are the way to go. It took a decade for mainstream cycling to catch up, but here we are...

Spring has come to the lowlands, but at 3,000 ft in the Cascade Mountains, it still looks like this. Trsting the new Flyway…

The new Salsa Flyway looks good on . This is the test bike, wearing 700x48 Poteau Mountain semi-slicks. The suspension fork and dropper post would come in handy on Poteau Mountain—the roughest part of the Arkansas High Country Race.

Head to the RH Journal for more details on the Flyway and why we’re excited about it. (Link in our bio.)

This year marks 20 years of our research into tire performance. Back in the spring of 2006, we started testing tires on real roads, with a rider on the bike. The results surprised everybody—us included: High pressure doesn’t make high-performance tires roll faster.

Now the Escape Collective has conducted a similar study of real-road tire performance. What they found is surprising, at least at first sight: The tire they tested rolled fastest at 75 psi, the highest pressure they tested. You may have seen the headline: “Get ready to rethink accepted wisdom.”

Time to throw out 20 years of testing and return to ‘high pressure = speed’? Not quite... Once we look beyond the attention-grabbing headline, the new results confirm something we have long suspected: Not all tires behave the same. To get the full benefit of the wide-tire revolution, you need supple tires.

Head to the RH Journal for a detailed discussion of how the Escape Collective’s results fit into the big picture—and how to set up your own tires for maximum speed (and comfort). (Link in our bio.)
