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.
