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.
Performance posture
A great choice for endurance road riders, trail riders and anyone who rides for speed and distance milestones.
OCLV Carbon shell
Uber-light carbon rails and shell provide a perfect balance of weight, strength and compliance.
Full cut-out
A full cut-out minimises soft tissue pressure and allows for a more powerful and comfortable riding position.
Minimally bonded padding
Minimally bonded padding has been optimised to shave weight and create a sleek, high-end aesthetic for a saddle that looks as fast as it rides.
Developed with the team
This saddle was built for our pro cycling team and has been tried and tested by the world's top athletes.
Fit for any rider
RSL is designed to work with a wide range of body types and is available in multiple sizes to provide the best individual fit.
Blendr integration
Attach a Blendr accessory mount directly to this saddle for clean light integration that leaves enough room for a seat pack. (Mount included with saddle)

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.

WARNING: Only use a Bontrager seatpost that has 7x10 rail clamps or has two seat clamp bolts. Non-approved rail clamps can cause the saddle rails to break, which could cause a loss of control resulting in serious injury or death.
