The BiSaddle EXT Stealth — Ultralight, Sleek, & Fully Adjustable

The BiSaddle EXT Stealth Cutout Saddle is exceptionally light and features a center cutout. The cutout is for those cyclists who want extra perineal relief but still want the ability to ride on the nose. The nose width ranges from 45mm to 70mm. The rear width ranges from 120mm to 165mm. (Width may be limited when the front or rear are adjusted to a wide position.) The cutout helps relieve genital numbness, saddle sores, and sit bone pressure.

BiSaddle believes that everybody's behinds are different. Off-the-rack bike seats fit just a handful of people. For everyone else, they have to compromise. Riding an off-the-rack saddle is like wearing shoes that are too small or pants that are too tight. The BiSaddle works around these problems, by allowing total bicycle saddle adjustability.

The BiSaddle EXT Stealth Cutout Saddle comes in titanium and chromoly steel rail variants.


  • 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

Makes a difference for comfort

My wife was having serious tailbone and soft tissue pain on her new hybrid bike, even with a Terry saddle. After some experimenting with the BiSaddle, she is now pain free on the bike. She's very happy with it.
