Steadfast Frame

FBM Steadfast Frame

The FBM Steadfast -- Dialed For Modern Trail Riding

A 74.25 degree head tube angle, 13.75" chain stays (slammed), and a 9.25" stand over height keep the bike stable yet still nimble to whip.

At high speeds and roasting a set you want to keep it simple; you don't want to have think of anything except that feeling.

We recommend a 28 tooth sprocket.

Handcrafted in the FBM Machine Shop in Ithaca, New York, USA
