Bontrager Aeolus RSL 51 Carbon Road Wheel

Bontrager’s marquee lightweight carbon road wheel in a 51 mm depth: designed for the ultimate in speed, stability and confidence in all conditions.

The ultra-light Aeolus RSL 51 is the perfect upgrade for a faster you. Created with Bontrager’s all-new three-dimensional modelling 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 51 mm rim profile for the ultimate in speed and versatility across all conditions. Tubeless Ready rims with a wider 23 mm inner width proven to roll with less drag add to the overall speed gains, while ultra-light hubs with DT Swiss 240s internals and a Ratchet EXP 36-freehub keep your ride smooth.

Other Features:

• Aeolus RSL wheels deliver a new dimension in speed. By utilising 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 tyre system. And we didn't stop there. We also optimised for rolling resistance, landing on a wider 23 mm inner rim width that's 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 tyre compliance means you can focus on what matters most: being the fastest you.
• Aeolus RSL’s 23 mm inner width provides a better aerodynamic connection with tyres and allows them to roll faster. This design also lets you run lower tyre pressures for a smoother, faster and less-fatiguing ride.
• Aerodynamically faster rim shapes and a wheel/tyre 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.
• RSL-level OCLV Carbon is the lightest and strongest available, and it lets us create the fastest rim shapes we possibly can.
• Easily set your wheel set up tubeless with Bontrager TLR rim strips, or use a rim tape system for the lightest set-up possible.Move over, tubulars! This is the fastest wheel and tyre 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.
• 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.
• Every set of Bontrager carbon wheels is backed by the Carbon Care Wheel Loyalty Programme. 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.
