New arms and a new shape for a new GENERATION.

EXPECTATIONS

ARMS RACE

For this generation we resculpted the arm shape for improved clearance and fit on a wider variety of mountain frames.  At 498g for the Girder is perfect for XC/Trail riding.

HD - HEAVY DUTY

We understand. You're hard on stuff.  The Girder-HD arm set is 545g as we beefed up the carbon for Enduro riders like you. So, if you tend to bang into things or sometimes take the "wrong line" we highly suggest you choose the Girder-HD.

HOME GROWN

From initial napkin sketches to the final production, the  Girder is home grown. Developed and made In-House at Praxis with our own hybrid "RTM+Filimant Winding" manufacturing methods.
