Shimano's BR-M4120 Disc Brake comes packed with value and is well-placed for entry-level cyclists to experience life off-road. The BR-M4120 features rapid and responsive braking performance to elevate your all-mountain riding experience. A shorter free-stroke moves the brake pads to contact the rotors with less lever-travel, meaning you're on the brakes faster and have more lever to squeeze to get the braking force for a specific section of trail. The M4120's I-SPEC EV lever clamp optimizes tuning to accommodate more fit options with the shift lever and braces the brake lever body against the handlebar for more stability under heavy braking.The caliper body brings powerful performance, when compared to lower-tier two-piston bodies, and packs responsive, reliable, and consistent braking.
