Description

When executing a historically accurate overhaul on a mid-century French frame, sourcing a fork with the correct steerer tube dimensions and thread pitch is critical. This second-hand steel fork delivers a classic profile engineered specifically for 700C and 650B setups, maintaining the structural alignment needed for dependable tracking and steering response.

Key Technical Features

Crafted from resilient classic steel, this component is designed to fit traditional lugged frames. The steerer tube offers ample length for fine-tuning your headset stack height, while the threaded portion allows for clean integration with vintage French headsets. As a used part, it exhibits light cosmetic signs of age and storage, such as superficial micro-scratches. Please note that the detailed photographs form part of the description to help you evaluate its aesthetic condition.

For restorers working on different frame heights, we also stock the slightly shorter 163mm Steel Fork for Bicycle Frame 25x100, as well as the taller Steel Bicycle Fork 208mm Steerer 25x100 option to ensure a precise dimensional match for your build.
