Bontrager Aeolus RSL Bike Saddle – 145mm

An ultra-light aero road saddle with a full cut-out that maximises power and minimises soft-tissue pressure for sustained comfort.

Dimensions 250 × 145 mm


Streamlined for speed, sculpted for comfort

The 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 the racers from Trek Factory Racing using uber-light carbon rails and a 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.
