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 145 mm saddle widths, while riders assigned female typically find the most comfort from 155 mm width saddles.
Aeolus Comp Bicycle Saddle
Aeolus features a full cutout that uses the latest biomechanical research to eliminate soft tissue pressure and maximise power and sustained comfort for riders in an aero road riding position.
Longer cutout
The split design of the full saddle cut-out extends from the nose through to the rear of the saddle to minimise 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 that the whole saddle is usable and comfortable, whether you’re sitting up on the hoods or hammering in the drops.
Added compliance
The rails are housed at the very front of the saddle which allows the entire saddle shell to flex and conform to the rider for increased compliance and added comfort.
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, as well.
Initial setup tips
Aeolus is optimised 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 10 mm of setback from the nose and a 2-degree downward tilt.
Compatible with Blendr Saddle Bag
Good news! This saddle is compatible with the Blendr accessory multi-mount to attach the Blendr Saddle Bag, Blendr Fendr and rear light. Carrying your flat kit, keeping your kit dry and clean, and being seen has never been easier.
30-Day Unconditional Guarantee
If for any reason you’re not satisfied with a Bontrager or Trek aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.

See the guideProper saddle adjustment
WARNING: Extended riding with a poorly adjusted saddle, or one that does not properly support your pelvic area, can cause injury to your nerves and blood vessels. If your saddle causes pain or numbness, re-adjust the saddle position. If, after adjustment, your saddle still causes pain or numbness, consult your Trek dealer about further positioning or replacing the saddle with one that better fits you.
