Key specifications - Front brake screw: 48 mm long, includes two 4.3 mm height washers. - Rear brake screw: 32 mm long, includes two 4.3 mm height washers. Design and performance benefits - Dual axis core design: Braking force is more sensitive and direct, providing precise control when stopping. - Self-lubricating bushings: Rotating parts reduce friction, helping minimize braking force loss and delivering stronger braking performance over time. - Symmetrical design: Equal force distribution between front and rear, resulting in smoother braking and reliable stopping power. Materials and durability - High strength aluminum alloy: Offers high toughness and wear resistance, with waterproof characteristics while remaining lightweight. Practical applications and use scenarios - Mountain or touring bikes: Upgrade braking performance for steep descents and variable terrain, enabling more precise modulation and consistent stopping power. - Road or cross-country bikes: Restore or improve braking feel on both front and rear, achieving smoother, more predictable braking performance. - Bike maintenance and repairs: Replace worn front and rear brake hardware with a matched kit that provides the specified lengths and washer integration, suitable for standard braking assemblies. Why this product stands out - Combines a dual axis core design with self-lubricating bushings to reduce friction and improve braking efficiency. - Symmetrical construction supports balanced braking response and safer stopping. - Constructed from high strength aluminum alloy for durability without added weight, improving performance in various weather conditions.
