BiSaddle SRT 1.0 – 100mm – 165mm (Adjustable)

Dimensions 198 × 165 mm


Available with CM and TI rails are round and will fit all seat posts. Carbon rails are oval and will only fit top clamp or oval specific seat post clamps.

Channel vs. Cut Out: A channel reduces some pressure in the middle of the saddle and provides more surface area for your sit bones to ride on. A cut out further reduces soft tissue pressure, but due to the reduction in saddle surface area the sit bone pressure may be a little higher.


You Can Adjust the Shape of BiSaddle to Custom Fit You!
Every body is different. Off-the-rack bike seats fit just a handful of people. For the rest of us, we’ve had to compromise. Riding an off-the-rack saddle is like wearing shoes that are too small or pants that are too tight.


You can adjust the shape of BiSaddle to custom fit your body and riding style. And, if your riding style or body shape change, you can simply re-adjust for ultimate comfort.
