Lewis LV4 4 Piston Hydraulic Bicycle Disc Brake Kit

Lewis took everything riders loved about the minimalist LV2 and turned it up with the LV4, a lightweight 4-piston hydraulic brake that brings serious stopping power to trail, enduro, and e-MTB riders without the premium price tag. Designed around a CNC-machined 7075-T6 aluminum caliper and lever assembly, the LV4 delivers rock-solid feel, smooth modulation, and heat-resistant performance when the terrain gets steep and fast.
