Why Is Your Old Saddle Causing You So Much Pain?

Traditional saddles were made to fit a single cyclist and chances are that cyclist is not you. Many cyclists struggle with hot spots, saddle sores and numbness in their genitals and general discomfort caused by an improperly fitting saddle. Riding a traditional saddle is like wearing shoes that are two sizes too small or pants that are too tight. If your sit bones are not properly supported or if your soft tissue is supporting your weight, then it is only a matter of time until you experience discomfort that can cause long term damage and destroy your ability to enjoy cycling.

Why Will You Fall In Love With A Custom Fit BiSaddle?

BiSaddle has an adjustable width and profile. This means you can custom fit your BiSaddle to perfectly fit your body shape and riding style. Even if you ride Road, Tri, Gravel and MTB you can tune BiSaddle to support your sit bones and remove pressure from soft tissue. This means you will finally be able to forget about your saddle and begin focusing on training harder, riding faster and having a whole lot more fun.

Replacement SRT and EXT surfaces can be used on all 3 bases including Chrome Moly Rails, Titanium Rails and the Full Carbon Base.


BiSaddle custom fit bike saddle surfaces are all considered medium firm with a gel pocket in the back for sit bone comfort. 


 All BiSaddle surfaces are universal fit and work with all of our saddle base frames.

 Perfect shape provides comfort for thousands of miles.

 SRT Surfaces are shorter than most all other saddles in the cycling industry. Best for MTB and Tri.

 EXT Stealth Surfaces have a center cutout which provides more room for the perineal area to help reduce numbness. Best for Road, Gravel and E-Bikes

 EXT Sprint Surfaces are shaped more like a short nose traditional saddle, but with adjustability. Best for all types of cycling including Tri, Road, MTB, Gravel and E-Bikes


* Note: This is the surface only. Does not include a custom packaging box or saddle base frame.
