Machined Bike Parts, By Type
Each page covers the interface standards you cannot change, the tolerances that actually matter, what the finish does to your dimensions and what a quotable drawing has to carry. Written for the person drawing the part.
- Stems and faceplates
Custom CNC Machined Bike Stems
Two clamp bores against fixed standards, a faceplate that has to close evenly and a rider on top of it.
- Chainrings and spiders
CNC Machined Chainrings and Spiders
A flat part with the tightest tolerance on the site. Tooth width decides whether a 1x chain stays on.
- Cranks and pedal hardware
Machined Crank Arms and Pedal Components
Fatigue critical, envelope fixed by the frame and the rider. The part where anodize choice changes test results.
- Hub shells and freehubs
Machined Hub Shells and Freehub Bodies
Turning plus milling in one part. Concentricity between the bearing seats decides whether it drags.
- Brackets, mounts and hardware
Machined Bike Brackets, Mounts and Hardware
The long tail. Low part cost, fixed interfaces, and finishing batch minimums that dominate the quote.
- E-bike drive hardware
Machined E-Bike Motor Mounts and Brackets
Machined like a bike part, loaded like a light vehicle part, regulated like an electrical product.
Not on the list?
If it starts as a block of aluminum and ends up bolted to a bike, send it. Frames, forks, carbon parts, wheels and anything molded are outside what we match, and we will say so on day one rather than waste your week.
Designing the part now? Start with the interface standards tables so the dimensions you cannot change are right before you tolerance the ones you can.
