Bontrager's all-new Aeolus RSL wheels are the result of a completely reimagined design process. In the past, Bontrager's optimisation process was done in 2D. For Aeolus RSL, Bontrager enabled 3D CFD models, which allowed engineers to accurately account for every gram of drag, in every direction, through every plane and across all aspects of the wheel/tyre system.

A third dimension in speed


With this new approach, Bontrager was better able to replicate real-world conditions and adjust the design accordingly, optimising for aerodynamics as well as rolling resistance.

The result is a wheel that moves way beyond marginal gains. Aeolus RSL wheels aren't just fast; they're the fastest wheels Bontrager has ever made.

Off-the-charts faster


Aeolus RSL wheels are significantly faster than all previous Aeolus models, and the speed gains don't come at the cost of stability.

Wider is faster


Aeolus RSL’s 23 mm inner width (21 mm on Aeolus RSL 37) 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.

Race-calibre carbon


All Aeolus RSL wheels are built with RSL-level OCLV Carbon. It's the lightest and strongest available, and the key to creating our fastest rim shapes ever.

Designed with the pros


To create a wheel set worthy of the Race Shop Limited (RSL) name, our engineers turned to Trek-Segafredo. The team's feedback helped us create the ultimate race wheel set, one that adds speed and confidence to every ride.

Faster with fewer watts


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 a similar depth.

New lightweight internals


Aeolus RSL wheels feature all-new lighter-weight Ratchet EXP freehubs built with proven DT Swiss 240s internals for consistent engagement and a smooth, fast-rolling feel.

Tubeless Ready (TLR)


Easily set up your wheel set 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 Factory Racing to give them an edge over the competition.

Confidence in carbon


Like all Bontrager carbon wheels, Aeolus RSL wheels are backed by 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.

Available Aeolus RSL wheel models


Aeolus RSL is available in multiple depths (37 mm, 51 mm, 62 mm and 75 mm), each designed to meet the demands of a specific kind of ride.
