Serotta Stainless Steel Brake Nut For F1, F2, F3, S3 Reynolds Ouzo Forks & ST Carbon Rear Ends

This is a small but essential part for any bike nerd rebuilding a classic Serotta or working with specific carbon forks.

It's a Serotta-branded brake nut, machined from stainless steel.

It's designed to work with F1, F2, F3, and S3 frames, as well as Reynolds Ouzo forks and ST carbon rear ends.

If you've lost one during a build or just need a fresh one, this is the exact replacement.

It's made in the USA, weighs next to nothing (just 5 grams), and is built to last.

It comes with a one-month warranty, but honestly, it's stainless steel—it'll probably outlast the bike.

Check the pics for exact dimensions, but it's the standard part for these setups.

Simple, effective, and keeps your brakes mounted safely.
