Description

This pre-owned steel bicycle fork is designed for classic frames utilizing 700c or 650b wheel standards. Tailored for precise restorations of vintage road setups or traditional touring bikes, it offers structural integrity for period-correct assemblies. Due to its vintage nature, some typical cosmetic blemishes and minor surface wear from extended storage are present. Note that the photographs form part of the description.

It provides excellent vibration damping inherent to traditional steel alloys, ensuring predictable steering response and tracking. If you are configuring a custom retro setup, you might also require a matching Front Headlight Bracket for Peugeot Mercier Motobécane Touring Bike to mount classic accessories directly to your front end.

  • Fork steerer (in mm): 150 -160

If your frame setup requires a slightly different height, we also carry other sizes including the 157mm Steel Bicycle Fork 25x100 as well as the slightly longer 163mm Steel Fork for Bicycle Frame 25x100.
