r3pro Caliper Alignment Tool for Hope E4 / RX4 / TR4 Brakes

Align Your Hope E4 / RX4 / TR4 Caliper Perfectly — Every Time

Designed and registered in the UK, the r3pro Caliper Alignment Tool takes the guesswork out of brake setup — precision-engineered for riders who demand consistent, rub-free performance from their Hope brakes.

Misaligned calipers cause brake rub, uneven pad wear, and lost power. This tool slots cleanly between your pistons and rotor, holding the caliper in the exact position needed to torque your bolts with confidence — no fiddling, no frustration.
