What makes Saddle unique? 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 Saddle 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.
