Dominate Every Trail with Professional-Grade Stopping Power Engineered for demanding mountain bikers, MEROCA's hydraulic disc brake system combines race-proven dual-piston technology with user-friendly features for uncompromised control. Why Riders Choose This Brake Set: Synchronized Dual-Piston Calipers: Twin pistons clamp the rotor symmetrically, eliminating uneven pad wear and rotor warping. The self-adjusting mechanism maintains consistent pad-to-rotor clearance for zero-drag pedaling. Integrated Oil Cylinder Advantage: Our patented one-piece reservoir amplifies hydraulic pressure, translating 30% less lever effort into stronger braking versus conventional systems—crucial when navigating rock gardens or switchbacks. All-Weather Reliability: Mineral brake fluid maintains viscosity from -20°C to 200°C, while corrosion-resistant CNC aluminum calipers withstand mud, river crossings, and winter road salt. Installation Made Simple: Universal Compatibility: Fits 22.2mm handlebars and standard IS/A-post mounts (51mm B-pillar, 75mm A-pillar) Clear Safety Guidance: Protective spacers (included) prevent accidental piston engagement during setup Pre-Bled Performance: Factory-tuned hydraulics require no bleeding—mount, align, and ride Technical Specifications: Model: HD-M800 (Color: Black/Red/Pink/Blue/Gold/Purple) Rotor Compatibility: Front F160/F180, Rear R140/R160 (6-bolt) Lever: 3-finger design with tool-free contact point adjustment Weight: Front 327g + Rear 311g = 638g/set Note: Always remove caliper spacers BEFORE squeezing levers to avoid oil seal damage.
