Concept site Switchback is a fictional gravel bike shop, designed and built by Patrick Bushe to show what I make for gravel bike shops. Fictional, by Patrick Bushe

Which size am I?

Your height picks the size. Your inseam checks it. We draw the frame to scale so you can see the room over the top tube.

Stand against a wall in socks with a book between your legs, spine up and snug. Measure from the floor to the top of the spine.

Sample Geometry and fit advice are part of the concept. The saddle height uses the common 0.883 x inseam starting point, measured from the center of the cranks to the top of the saddle. A shop fitting beats any calculator.

Checkout would open here

Switchback is a concept store, so nothing is for sale.

A real Switchback store would go to Shopify checkout here, with in-shop pickup and fitting as an option.
