Our customized bicycle bottom bracket nut is designed for high-performance locking and durability. Featuring a serrated flange nut bicycle design, it effectively prevents loosening even under high-intensity vibration during cycling. This crankset locking screw is precision-machined from high-strength steel with professional surface treatments (black oxide or zinc plating) for superior rust resistance. Ideal for universal repairs of center axes and MTB cranksets, it ensures a secure fit and smooth power transfer for your bike.
As a top-tier precision machined parts supplier, we support 3-day prototyping and 7-day batch delivery. Our in-house lab ensures 100% strict quality control, backed by ISO 9001/14001. We provide technical DFM feedback and manufacturing scale for global supply chains.
Accelerate your product development with our comprehensive custom cnc milling services. Our facility is optimized for cnc machining prototypes, allowing for rapid iteration of complex housings, structural brackets, and intricate industrial components. We handle a vast range of materials, specializing in anodized cnc aluminum parts with vivid surface finishes, as well as precision-turned stainless steel rods and custom polymer components. Our capabilities include high-gloss mirror polishing and multi-part assembly fitment. Whether you need a single functional prototype or a bridge to mass production, we provide DFM feedback and 100% inspection to ensure every dimension matches your STEP/IGS files.
Source hardware directly from a trusted precision turned components manufacturer. We produce custom knurled thumb screws and diverse brass cnc machining parts, including nozzles and standoffs. Using CNC lathes and Swiss technology, we achieve tight tolerances and intricate knurling patterns (straight or diamond). We also process stainless steel and aluminum into ball studs and turned fittings. Whether for prototypes or production, we offer ready stock and full customization. Nickel plating and passivation are available for longevity.
Optimize your chassis with our high-precision cnc machined mountain bike parts. This collection focuses on full-suspension frame optimization, featuring lightweight 5-axis milled cnc suspension rocker arms and essential custom bike frame components. Our expertise in mtb suspension linkage manufacturing ensures that complex pivot points and shock mounts are held to micron-level accuracy, providing a stiffer and more responsive ride. We provide ready stock and full OEM/ODM services for frame builders.
Elevate your builds with our CNC bicycle parts and precision CNC turned parts. This collection features machined aluminum cranksets, chainrings, cassettes, and brakes, alongside high-precision drivetrain components. Our custom machined bike components leverage 5-axis milling and Swiss-style turning for tight tolerances and exceptional finishes. We provide ready stock and full OEM/ODM services.
This custom CNC machining parts capability runs through a single CNC machining service — send STEP, STP, IGS, DWG or PDF and receive finished metal and plastic components held to ±0.005mm where the feature allows. We run CNC milling, CNC turning and 5-axis machining, plus surface finishing; the aluminum CNC machining service sits alongside Stainless 304/316, Titanium Gr.2, Brass C360, PA6, PEEK, POM, acrylic, phenolic and carbon fibre. Engineering support covers DFM analysis, design optimisation, prototype validation and material selection. Prototypes ship in 3–5 days, quotes return within 24 hours, and production carries 100% inspection with CMM.
