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

The BiSaddle EXT Sprint Saddle does not have a center cutout, but 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.

You can adjust the shape of BiSaddle EXT Sprint 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 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 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 Sprint Saddle comes in titanium and chromoly steel rail variants.

I�ve always thought that riding was bound to have some level of discomfort, but man was I wrong. I�ve had a bit over a year of frequent saddle sores and pain to the point where I couldn't ride multiple days in a row. Purchased this saddle as a �last resort� after trialing a bunch and am SO glad I did. I can finally ride comfortably in the aero position! It took a few tweaks to find the right configuration but was well worth it. By far the best purchase I�ve made for my bike.

An interesting saddle.

I was developing a couple of hotspots and began thinking about a different saddle after trying several different positions. Running over a water bottle cost me 4 broken ribs and a weird break to my clavicle. So, my riding has been on a Neo2 and a Tacx Vortex. First, a warning: this saddle is thicker than the SMP Glider I was using. If you are short, like me, you may have to cut some seatpost. This saddle gave me the opportunity of trying out numerous widths and positions. I got it on sale. This combination made it more than worthwhile. I like the padding. I have not tried every combination of the saddle, but this is the equivalent of being able to try out a lot of saddles. It is shorter than I thought (not a bad thing).
