CNC Milled Brake Lever Components for High-Performance Bicycles

CNC-Milled High-Strength Aluminum Alloy Brake Lever

This brake lever is crafted from high-strength aluminum alloy AL7075-T5 using precision CNC Milling, featuring a compact design with smooth, fluid lines. The surface is finished with a high-luster black coating—such as PVD or hard anodizing—delivering a mirror-like finish for both aesthetic appeal and durability. The front end boasts a streamlined, rounded conical head for ergonomic handling, while two longitudinal parallel grooves in the middle enhance anti-slip performance and operational stability. The rear section extends into a gently curved flat lever arm, complete with mounting holes at the end for secure hinge or bolt connection to the braking mechanism.

Manufacturing Process Overview

1. Initial Material Preparation: The manufacturing process begins with precise cutting of raw AL7075-T5 aluminum alloy stock, removing excess edges and sharp angles to prepare for high-precision machining.
2. High-Precision CNC Milling: Using a pre-programmed digital blueprint, complex features—including the aerodynamic profile, non-slip grooves, and exact mounting hole positioning—are milled in a single operation. Advanced CNC technology ensures dimensional accuracy within micrometer-level tolerances, guaranteeing a perfect fit with the braking system and eliminating any potential gaps or control inconsistencies.
3. Gloss Black Anodizing Finish: After machining, the lever undergoes direct gloss black anodizing via electrochemical treatment. This forms a dense, wear-resistant aluminum oxide layer on the surface without requiring prior sandblasting. The result is a uniformly glossy black finish that preserves the fine details of the CNC-milled texture while significantly enhancing corrosion resistance—ideal for outdoor cycling applications and extended product lifespan.
