Aeolus RSL Tires - sprint ahead with the fastest road tires

Our fastest Bontrager tire ever

Race day is every day with the fastest-ever Bontrager tire. The all-new Aeolus RSL tire saves 3.7 watts in rolling resistance over R3 TLR, and even more watts in aerodynamics.

And a huge increase in speed and aerodynamics aren’t the only noteworthy characteristics of Aeolus RSL. Its 320 TPI cotton construction with light and strong fibers provides top-shelf suppleness by better conforming to road surfaces. Pair all of that with additional sub-tread puncture protection, and Aeolus is ready to take you to the podium. Aeolus RSL tires are made to soar over miles of road no matter your riding preference or tire clearance, with options in 26, 28, 30, and 32c sizes.

+3.7 watt savings

The new Race Dual-Compound places firmer rubber at the center tread and softer rubber on the shoulders for cornering traction resulting in a +3.7-watt savings in rolling resistance over R3 TLR. (R3 TLR 28c vs. Aeolus RSL 28c at 22mph (35km/h) and 150lbs. (68kg) of load on a single tire using Trek's in-house treadmill).

Tires with a tailwind

The new design cultivates impressive aerodynamic gains, helping you save additional watts and gain so much free speed, you’ll feel like you have a tailwind following wherever you roll. (R3 TLR 25c vs. Aeolus RSL 28c, mounted on Aeolus RSL 51 wheel)

Crafted with cotton

A 320tpi cotton casing with more flexible fibers offers the comfort and speed by better conforming to road surfaces. The result is a smoother, faster, and grippier experience.

Flat-free racing

Ride easy with the confident flat protection of a Tubeless Ready setup. Crafted with a sub-tread breaker belt directly under the tread for an extra hit of protection from road debris.
