⭐⭐⭐⭐⭐ "I Started Using a BiSaddle onAug. 27th and Have Ridden Approx. 800 Miles and Have NOT Had a Case of Numb Nuts Since! Very Happy With My Purchase!" -David B.
⭐⭐⭐⭐⭐ "I thought constantly moving around on my seat to get comfortable was normal. At least that is what all my friends told me. The Sprint is the first saddle that feels like it fits me instead of trying to make my body fit the seat. Finally no more moving around!" -James Clarkson
⭐⭐⭐⭐⭐ "I ride a pretty aggressive aero position and never found or liked specific triathlon saddles.I tried the EXT Stealth model and this is so super comfortable. Not so wide as the ISM models so much more room for the thighs. The back of the saddle is adjusted a little wider so when I sit up right there is support in the sit bones.By far the best and most comfortable saddle I have ever ridden." -Jeroen
⭐⭐⭐⭐⭐ "I first tried my BiSaddle on my Madone in June and have fallen in love. Game changer! I have a hard time staying in aero on the trainer with my tri bike and have my first Ironman in 2021 - I’m going to give bisaddle a shot there too!" -Susan L.
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 andnumbness 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.

BiSaddle Bike Saddle Comparison Guide
Sprint
Preferred by Road cyclists
Thinner nose relieves inner thigh rub
Reduces leg numbness
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.
Stealth
Preferred by Road and Time Trial Cyclists
Center cutout relieves perineal pressure
Reduces soft tissue pain and pressure
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.
SRT
Preferred by Tri, Gravel, XC and MTB Cyclists
Extra short nose helps you stay in aero or the drops for a longer time
Reduces saddle sores and hotspots
The SRT is shorter than most other 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.
