Bontrager Aeolus Comp Bike Saddle Model 581638 250mm x 155mm , weight 289g, Rail Dimensions Round 7 x 7mm (Standard)

Comfort without sacrificing power

Aeolus Comp brings comfort, power, and speed to road riders looking to dig deep and rotate further forward into a more aero road position. Added padding make it the go-to saddle for anyone who wants to comfortably get the most out of their aero road bike. A shorter overall length with a wider nose and full cut-out ensure targeted support that eliminates soft-tissue pressure.

Find your saddle size

We make saddles for all riders, and the most comfortable saddle is the one that best suits your anatomy. Riders who are assigned male tend to have narrower pelvis bones and are best suited for 145mm saddle widths, while riders assigned female typically find the most comfort from 155mm width saddles.
