Saddle Pain isn't an Option.

Introducing the worlds only Adjustable Shape Saddle

Even a small amount of Pain or Numbness in your unmentionables can spell disaster and lead to loosing your ability to cycle.

Being able to adjust the shape of BiSaddle means you can make all those adjustments you have dreamed of to get that perfect fit.

50.50.50. "The Iron Cowboy"

James Lawrence "The Iron Cowboy" is the world record holder for completing 50 Ironman races in 50 consecutive days. With that much cycling James was bound to feel every painful saddle rub, bump and pressure point. Because you often need to break your own wind in a triathlon, James found himself cycling in the aero position, which on his old saddle would cause numbness within 30 seconds of riding. 


With BiSaddle, James has been able to adjust its' shape to alleviate hotspots, abductor rubbing and achieve no more numbness when riding in aero.

What makes BiSaddle different?

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.
