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.


The SRT is the shorter model at 198mm length.  Looking for longer?  Check out the 243mm EXT Model.

How it works:

  • The saddle consists of two individually adjustable surfaces that have two points of adjustment each (front and back, meaning there’s LOTS of adjustability)
  • These surfaces are contoured to fit the curvature of the bottom bones of your pelvic girdle (Ischiopubic rami and Ischial Tuberosities to be exact.)
  • These surfaces are mounted on a frame that allows the surfaces to be positioned to allow for both separation and angular variations.
  • This design addresses erectile dysfunction in men by allowing for up to 3/4 inch of separation of the surfaces in the front, which is where the dorsal artery passes under the pubic symphasis (bottom of the V) and into the genitals.
  • By only supporting riders on the bones at the bottom of the pelvic girdle, it also eliminates pressure on the perineum.

Customer reviews:

"I have been riding the Bi-saddle for 8 months.  I have the cr-mo rail saddle.  I am able to ride daily.  My background is a 7 time age group Tri All American.  This saddle was a game saver!  Why?  Because i was just about to give up cycling due to saddle discomfort related to an enlarged prostrate."
-Duane M.


I was convinced everyone was as uncomfortable as I was on the bike, and everyone was just lying. I had multiple bike fits and tried about a dozen saddles and had just about given up.  I’m only a week and 100 miles in, but I’m sold.  Installation was really simple. I knew the initial setup it came in wasn’t going to work, but I followed the directions, sat on it, and quickly knew what needed changed. One adjustment is all it took.

I have been through numerous saddles over the years including ones that I chose during bike fits. While some were better than others none have remained comfortable on anything other than short rides. I have had consistent saddle sores and worrying numbness on longer rides. I do a lot of my Ironman training indoors on the trainer and that brings a whole new level of discomfort to long hours in the saddle. Towards the end of last year I tried the BiSaddle SRT for the first time. Out of the box, it was on par with the best that I have tried previously but by the end of a few weeks of micro-adjustments, I knew that I had finally found my match. I have made a few tweaks since then, including using the flattening wedge and I couldn't be happier.  I have since added the EXT model to my road bike.
