Paul Components are Handmade in Chico CA, USA using the highest grade materials available by experts in bicycle component craftsmanship.
These cranks use a specially designed interlocking chain ring/crank interface. Four 7075 Aluminum chain ring bolts with T25 Torx heads bolt through the chain ring and into the reinforced spider on the crank arm.
We machine the crank arms from 2024 aluminum, a very strong and stiff material. They are given a high polish finish and optional black anodization. We currently make the Road Crank in two lengths: 165mm and 170mm.
The chain rings are machined out of 6.3mm thick aluminum plate; very sturdy. They're currently designed only to work with 1⁄8" chains (track and bmx), and are unpolished. Replacement chain rings are available.
