White Industries manufactures precision bicycle components

White Industries, based in Petaluma, California, produces precision-machined bicycle components, including seat collars and integrated headsets.

The company's seat collars are machined from 6061 aluminum and feature a bolt interface with a bronze pin nut designed to ensure even clamping force and prevent binding. These components are available in various sizes and colors, including black, silver, blue, purple, and gold.

Additionally, White Industries manufactures IS42/IS52 threadless headsets designed for frames with integrated 42mm/52mm head tubes. These headsets are constructed from U.S.-sourced 6061-T6 aluminum and are compatible with both tapered and straight fork steerers. The headsets utilize replaceable Enduro bearings and feature machine-engraved logos.
