• All-Metal Brake Pad for High Performance : Built with an all-metal brake pad that resists calcification, friction, and high temperatures, ensuring powerful braking even under extreme conditions. The friction material, enhanced with copper fiber, improves heat conduction and friction, thus addressing issues like noise, dust, and heat degradation, ultimately boosting braking efficiency. Ideal for muddy and sandy environments.
• 4 Piston Braking Mechanism for Stability : Ordinary single-drive disc brakes may cause disc deformation and uneven wear. Our 4-piston dual-drive caliper brakes clamp both sides of the disc simultaneously, ensuring equal force and synchronous friction. This design surpasses typical double-piston brakes, offering superior stability and preventing disc deformation. When the brake lever is engaged, oil pressure instantly transmits to all four pistons, pushing the brake pads and locking the discs fo
• Ergonomic Brake Lever Design : Features a single/double finger brake handle for easy Attain and stroke. The frosted, non-slip handle with an integrated oil cylinder boasts strong sealing and reduced maintenance. Lightweight and compatible with most market models, its 22.2mm installation diameter fits a wide range of bicycles.
• Brake Hose Construction : The brake hose is crafted from high-quality PVC, offering waterproof, moisture-resistant, and age-resistant properties. The oil injection line pipe maintains excellent sealing and heat dissipation, essential for transferring heat from the clamp to the oil pipe.
• Special for Longevity : The main body is crafted from upgraded 6061 aluminum alloy, with a baked matte paint coating for resistance. Fully enclosed corners ensure waterproofing, dustproofing, and complete sealing for safe, maintenance-free use.
