An ultra-light aero road saddle with a full cutout that maximizes power and minimizes soft-tissue pressure for sustained comfort.

Streamlined for speed, sculpted for comfort
Aeolus RSL brings comfort, power, and speed to cyclists looking to dig deep and rotate further forward into more aero positions. The Race Shop Limited design was developed with racers of Trek Factory Racing using uber-light carbon rails and shell that meld together with minimal padding for a saddle that looks fast as it rides. A shorter overall length, wider nose, and full cut-out eliminates soft-tissue pressure.

Aeolus RSL Bicycle Saddle
Aeolus RSL utilizes the latest biomechanical research and a full cutout design to eliminate soft tissue pressure and maximize power and comfort for riders in an aero position.

Longer cutout
The split design of the full saddle cut-out extends from the nose through to the rear of the saddle to minimize soft tissue pressure and allow for a more powerful, rotated position.

Wider nose
Aeolus has a wider nose with a shorter overall length that ensures the whole saddle is usable and comfortable, whether you’re sitting up on the hoods or hammering in the drops.

Fit for any rider
Aeolus is designed and tested to work well for a wide range of riders of any body type and gender, and is available in multiple sizes to provide the best individual fit.

Blendr integration
You can get a Blendr accessory mount that attaches securely to the rear of this saddle for clean integration with any Bontrager Flare rear light. There's still enough allowance for a seat pack, too.

Initial setup tips
Aeolus is optimized for the best fit and performance, so it’s slightly shorter than a traditional saddle. When swapping out your old saddle, we suggest starting with an extra 10mm of setback from the nose and a 2 degree downward tilt.
