The Shimano Deore M6200 2-piston disc brake pairs the BL-M6200 SERVO WAVE lever with the BR-M6200 2-piston caliper for a complete hydraulic brake system that prioritizes modulation and weight savings. SERVO WAVE delivers rapid pad contact and a progressive power curve, while the 2-piston caliper keeps overall system weight down without giving up consistent, reliable stopping. What Our Gearhead(R) Experts Are Saying:"The 2-piston caliper and SERVO WAVE lever give the system a light, progressive feel that suits riders who want precise control over braking force on technical terrain. The weight savings over a 4-piston setup add up across a full build."
