EXT Adjustable Shape Saddle

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

The EXT is long enough to be UCI compliant

EXT is favored by road and time trial cyclists

The extended nose on the EXT is desirable for nose riding

BiSaddle Model Comparison

Preferred by Tri, Gravel, XC and MTB Cyclists

The SRT is shorter than most noseless saddles. This helps you relieve perineal pressure by eliminating the nose.The nose width ranges from 45mm to 70mm. The rear width ranges from 125mm to 165mm. (Width may be limited when the front or rear are adjusted to a wide position.) 

Our all around most comfortable saddle helps relieve saddle sores, numbness, chafing, sit bone pressure, and general discomfort.

Preferred by Road, E-Bike and Time Trial Cyclists

The EXT Stealth has 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.)  Helps relieve genital numbness, saddle sores, and sit bone pressure.

Preferred by Road, E-Bike and Time Trial Cyclists

The EXT Sprint does not have a center cutout. Removing the cutout allows for a more narrow saddle. If you have experienced inner thigh rub on your current saddle, then the Sprint is for you. 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.)  Helps relieve leg numbness, thigh chafing, and hot spots.

BiSaddle universal flexible base frame absorbs jolting road bumps from rattling your teeth!


Our Flex Frame is made right here in our USA factory in St. George, UT. We take pride in our work and are constantly innovating to make BiSaddle the most durable, yet light weight custom fit bike saddle in the world.


Our Carbon Frame is full carbon and is about 40 grams lighter than the chrome moly rail flex frame. If you are looking for a more rigid saddle, then a full carbon frame is what you are looking for. 


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

 Longer rails allow for extra adjustment on your bike.

 Chrome Moly Rails are super tough and durable. Great for MTB and Gravel!

 Titanium Rails are almost 20 grams lighter than the Chrome Moly Rails. They are very durable and are best for all types of cycling including Tri, Road, MTB, Gravel and E-Bikes

 Full Carbon Frame is not meant for MTB and Gravel. It is best for Tri and Road. It is super light and has a rider weight limit of 210 pounds.

 Lifetime warranty on frame against manufacturer defects.


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

Replacement SRT 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
