Race day has a way of exposing everything. Every gap in fit, every shortcut in assembly, every part that was almost right.

There is no time to think about the bike out here. Just the trail, the line, and the next few seconds.

That is the standard we build to at Rotation. Not "good enough for most rides." Good enough for this one.

Light where it counts. Built to win.

Meet the RaceLab XC30, a hookless tubeless mountain wheelset built for World Cup level cross country racing.

The details that matter:
▸ 25mm depth, 30mm internal width
▸ Hookless tubeless bead profile for a secure, planted contact patch on loose or rocky terrain
▸ 1200g wheelset (±40g), light enough to help you climb and accelerate faster
▸ Rotation Axis Pro or DT Swiss 240 hubs
▸ Hand built in-house with spoke tension measured and balanced to exact tolerances

The kind of wheel you install, trust, and stop thinking about.

Some rides are about the numbers.
Some are just about being out here with people who get it.

No creaks. No mid-ride adjustments. No one falling behind to fix something that should have been checked before the ride started.

Just three riders, one trail, and gear that let them focus on each other instead of the bike.

Ride harder. The details are handled.

Riding bikes + talking bike tech 👌. Our idea of a great weekend! We love designing products, but we like riding them and pushing them just as much so we can make them even better.

Bottom brackets, hubs, wheels, wax. The parts you don't look at are the ones that decide how a ride feels. Ours are handled, checked, and finished by real people in Ellington, Connecticut.

Ride harder. The details are handled.

WR35 vs. R35? Which are you going with?

Both RaceLab wheelsets start with a 35mm carbon rim, hooked tubeless-ready construction, 24-hole spoke count, DT Swiss Aerolite spokes, and a verified 1250g ±40g wheelset weight.

R35 — Road
• 35mm depth
• 21mm internal width
• 0mm spoke offset
• 1250g ±40g
• Built for climbing, acceleration, and responsive all-around road performance with narrower tires

WR35 — Wide Road / Gravel
• 35mm depth
• 25mm internal width
• 2.5mm offset spoke bed
• 1250g ±40g
• Optimized around wider road and gravel tires for a more planted ride, cornering confidence, comfort, and stability over rougher surfaces

Same shallow, responsive 35mm platform. The choice comes down to how you ride.

R35: traditional road focus, light and responsive.
WR35: wider tire support, more volume, more composure.
