The ultralight Aeolus RSL 51 is the perfect upgrade for a faster you. Created with Bontrager’s all-new three-dimensional modeling design process, the all-new Aeolus RSL delivers a step-change in speed without sacrificing stability. It’s built with the lightest RSL-level OCLV Carbon, shaped into a new 51mm rim profile for the ultimate in speed and versatility across all conditions. Tubeless Ready rims with a wider 23mm inner width proven to roll with less drag add to the overall speed gains, while ultralight hubs with DT Swiss 240s internals and a Ratchet EXP 36-freehub keep your ride smooth.
All Bontrager carbon wheels are warrantied for life for the original purchaser and come with the added protection of Carbon Care. If you structurally damage your wheels while riding in the first two years of ownership, we'll replace them. It’s that easy.

Our fastest wheels ever
Aeolus RSL wheels deliver a new dimension in speed. By utilizing 3D models throughout the iterative design process we were able to more accurately account for every gram of drag, in every direction, through every plane, and across all aspects of the wheel and tire system. And we didn't stop there. We also optimized for rolling resistance, landing on a wider 23mm inner rim width proven to roll faster.

By completely rethinking our design process for Aeolus RSL, we moved way beyond marginal gains. Enabling 3D CFD models in our iterative feedback loop and incorporating more variables that affect speed, we were able to better replicate real-world conditions and make wheels that aren’t just faster but represent a step-change in speed.
Aeolus RSL wheels aren’t just faster, they also make you more efficient with less wasted energy. Plus, they offer more stability and more tire compliance means you can focus on what matters most: being the fastest you.
Every set of Bontrager carbon wheels is backed by the Carbon Care Wheel Loyalty Program. In the unlikely event that you damage your Bontrager carbon wheels within the first two years of ownership, we’ll repair or replace them for free.

Carbon wheels can lighten your ride and improve your performance—and when you ride Bontrager, your investment is protected. All Bontrager carbon wheels are backed by a lifetime warranty for the original owner.
Aeolus RSL’s 23mm inner width provides a better aerodynamic connection with tires and allows them to roll faster. This design also lets you run lower tire pressures for a smoother, faster, and less fatiguing ride.
Easily set your wheelset up tubeless with Bontrager TLR rim strips or use a rim tape system for the lightest setup possible.
Move over, tubulars! This is the fastest wheel and tire system available, and it’s exactly what’s raced by Trek-Segafredo to give them an edge over the competition
The all-new lighter-weight Ratchet EXP freehubs are built with proven DT Swiss 240s internals for consistent engagement and a smooth, fast-rolling feel.
RSL-level OCLV Carbon is the lightest and strongest available, and it lets us create the fastest rim shapes we possibly can.
Aerodynamically faster rim shapes and a wheel/tire profile proven to reduce rolling resistance add up to major watt-savings. For a rider like Trek-Segafredo's Mads Pedersen, Aeolus RSL can save 34 watts in a sprint finish over previous Aeolus wheels of similar depth.
If for any reason you're not satisfied with a Bontrager aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.
