Product Details
Core Machining Advantages
Cutting-edge Equipment: Our facility is equipped with imported 4-axis and 5-axis CNC machining centers, Swiss-type lathes, and CNC turning machines, enabling the single-setup production of complex curved surfaces and high-precision holes.
Rigorous Quality Control: We utilize Coordinate Measuring Machines (CMM), surface roughness testers, and hardness testers. Operating under the ISO9001 quality management system, we meticulously control every hole diameter and chamfer to ensure a perfect fit during assembly.
Extensive Material Expertise: We specialize in machining metals such as 7075/6061 aluminum alloys, TC4 titanium alloys, and stainless steel, meeting the demanding requirements for lightweight construction and high strength in bicycle components.
Surface Finishing: With our in-house anodizing workshop, we offer a range of finishes-including anodizing, sandblasting, polishing, and PVD coating-along with custom color options (red, blue, black, titanium gray, etc.), ensuring your parts deliver both outstanding performance and striking aesthetics.
Our Manufacturing Capabilities | From Prototype to Mass Production
Tackling complex structures and bringing design blueprints to life-we excel not only in the mass production of standard parts but also in overcoming the challenges of machining complex, non-standard components for the bicycle industry.
Precision Standards
Machining Precision: Consistently controlled within ±0.01mm to ±0.005mm.
Surface Finish: Ra 0.8 to Ra 0.4 (mirror-like finish achievable).
Key Process Highlights
5-Axis Simultaneous Machining: Handles complex aerodynamic tube profiles; enables multi-face machining in a single setup, eliminating tool-transition marks.
Deep-Hole/Complex-Profile Drilling: Precision machining of hydraulic brake channels and internal cable routing paths, ensuring smooth, unobstructed flow.
Thread Machining: Utilizes thread milling for high strength and clean threads; ensures bottom bracket and pedal threads meet specifications on the first pass.
Customization Process
Customization based on drawings (STEP/IGS formats supported) → Free prototype evaluation → Small-batch testing → Full inspection prior to shipment.
Product Applications | Our components are at the heart of the ride
Precision machining for parts across all major bicycle systems
Our CNC components are widely used in mountain bikes (MTB), road bikes, and gravel bikes. Key machined parts include:
Drivetrain
Chainrings/Cranksets: CNC-machined chainrings with intricate cutouts, minimizing weight while maintaining rigidity.
Rear Derailleur Cages: CNC-machined cages made from ultra-hard aluminum alloy or carbon fiber composites for faster shifting response.
Cassette Lockrings: Anodized, colorful lockrings that add a stylish touch to the wheelset.
Brake System
Brake Caliper Bodies: CNC-forged monoblock calipers offering excellent hydraulic sealing and powerful braking force.
Brake Levers: Ergonomically contoured CNC levers with fine anti-slip texturing for safer control.
Disc Brake Rotors (Center Lock/6-Bolt): High-precision cut heat-dissipation slots to effectively reduce brake fade.
Cockpit System
Stems: 4-axis CNC machined with a sharp, aggressive profile; ensures strong clamping force and eliminates unwanted noise.
Shifter/Brake Levers: Precision-sculpted thumb contact areas for a comfortable feel.
Handlebar End Plugs/Grip Locking Rings: Metallic detailing that highlights premium quality.
Wheelset & Suspension Systems
Hub Shells: CNC-machined shells with high-precision bearing seats to ensure smooth wheel rotation.
Fork/Shock Pivot Axles (CNC Axles): High-strength stainless steel or titanium alloy axles; wear-resistant and rust-proof.
Thru-Axles: Lightweight CNC hollowed-out design featuring a lockable hex key head.
Headset & Bottom Bracket (BB)
CNC Aluminum/Titanium Headset Caps: Distinctive designs that enhance the aesthetics of the head tube.
BB Sleeves/Locking Bolts: Precision-machined threads to eliminate noise and creaking in the bottom bracket.
Other Accessories
Water bottle cage bolts/plugs: Lightweight CNC-machined titanium alloy bolts.
Cycle computer/action camera mounts: CNC-machined from a single piece for stability and zero wobble.
Chain guide/stabilizer: CNC-machined protective components designed for Downhill (DH) and All-Mountain (AM) bikes.
