r3pro Piston Release Tool for SRAM Guide & G2 Brakes

Free Seized Pistons in SRAM Guide & G2 Brakes — Fast

Designed and registered in the UK, the r3pro Piston Release Tool was the first of its kind — precision-engineered for riders who won't compromise on their brake service tools.

Seized pistons kill brake feel and stopping power. This tool slots cleanly into SRAM Guide and G2 calipers and applies even, controlled pressure exactly where it's needed — no improvised tools, no scratched pistons, no frustration.
