Right Arm Repair Clamp

Product Description

Signature Series

The Right Arm Repair Clamp is the only seatpost-specific bicycle repair clamp made, and enables faster repair turnarounds. This unique clamp grips round or aero posts up to 110mm wide with precise pressure control, and the clamp is durable and rigid. Balanced rotation with the Right Arm reduces interference when positioning the bike, and its design doesn’t have hazardous sharp edges. The Right Arm Repair Clamp fits the most popular stands and each clamp is carefully handmade in the U.S. Nothing is faster, more versatile, more durable, or nicer to the bike than the Right Arm Repair Clamp!

Previously, standard bike repair clamps were four inches high with a contact radius designed for frame tubes. This design meant mechanics raised seatposts and “shimmed” the clamp faces with rags, which isn’t ideal. After 25 years and countless hours wasted with standard bicycle repair clamps, Brett Flemming developed the Right Arm, a unique repair clamp that only requires 2″ of exposed seatpost for use. The offset design gives mechanics balanced rotation for less effort and a more compact work area. The Right Arm also enables multiple height options and the clamp’s leather pads improve gripping power. 3 moving parts with ultra-precise tolerances for super-low maintenance.

Save time on every single repair. Save electrical tape. Never risk stripped fasteners, crooked saddle alignment, height errors, or concerned clients again. Forget adapters like add-on top tubes or clamps to clamp in your clamp. Show your customers you care about their beloved bicycles and their fit as much as they do, all while making your turnaround measurably faster on every repair. 

Conservative return on investment calculations show one Right Arm clamp saves a busy service department about 10 minutes per day per workstand, which translates to more than 60 hours per year. EVT customers often find the Right Arm pays for itself in well under a year and is built to last.

Replacement leather/epoxy kits are available on our website for purchase. The Right Arm’s new Nylatron bearings reduce the chance of crushing posts with excessive applications of force. Steel bearings are still available for older clamps.
