About this item

  • BITE POINT & LEVER REACH ADJUSTMENT: The Lewis LH4 Hydraulic Disc Brake features patented dual adjustment for bite point and lever reach, offering precise customization for your braking feel. The tool-free lever reach adjustment allows quick and effortless fine-tuning on the go, while the bite point can be adjusted using an Allen key for even more detailed personalization. This system ensures you can tailor your brakes for optimal performance and comfort, giving you confidence on any trail.
  • CNC 7075 T6 ALUMINUM FOUR-PISTON CALIPER: The CNC-machined 7075 T6 aluminum caliper delivers exceptional rigidity, enhancing braking performance while maintaining stability and predictability. Its robust yet lightweight design ensures reliable power modulation across all trail conditions, whether tackling steep descents or technical terrain.
  • ENHANCED LEVER BLADE: The Lewis LH4 brake system features a lever blade extended by 6mm, providing a more aggressive leverage ratio for enhanced braking strength. This design improvement delivers stronger, more responsive stopping power, giving riders confidence on technical descents and challenging trails. Paired with Lewis' patented dual adjustment system for reach and bite point, it ensures powerful braking without compromising ergonomic comfort.
  • 14MM + 17MM ASYMMETRIC PISTONS: The 14mm and 17mm asymmetric piston setup in the Lewis LH4 brake caliper ensures superior braking performance and efficiency. This design enhances the linear feel of the brakes, providing precise modulation and control for varying trail conditions. By evenly distributing pressure across the brake pads, it promotes balanced wear, extending pad life and maintaining consistent stopping power.
  • FOUR PRECISION LEVER BEARINGS: The Lewis LH4 brake system integrates four precision bearings into the lever blade pivot, delivering smooth and stable lever action. Each pivot point is reinforced with bearings on both sides, minimizing friction and maximizing responsiveness. This design ensures a precise, consistent braking feel, enhancing the overall control and functionality of the braking system.
