Whether you are riding to the corner store or across the country,you should be comfortable on your bike.
If you have back,neck,knee pain,saddle sores, or hand and foot numbness, your bike probably doesn't fit
you properly.
A bike should fit you.It should accommodate your body,your interests and style as a rider.
Your equipment should never "work against you" or "make you work harder".

To help people experience the joy and wonder of cycling, we want to make sure no one stops riding a bicycle due to pain or discomfort.

Each rider needs a different fit based on a variety of factors, Joseph Kuosac bike fit system offers your needs.
