What Is a Cantilever Brake Boss?

The cantilever brake boss (also known as a brake stud or brake post) is the threaded mounting point that is welded or brazed into bicycle fork legs and seat stays to accept cantilever or V-brakes. These bosses are essential for:

🚲 V-brakes (linear-pull brakes) – Common on mountain bikes, hybrids, and touring bikes
🛡️ Cantilever brakes – Traditional choice for cyclocross, touring, and vintage road bikes

Installation Notes

The cantilever brake boss is typically TIG welded or brazed into the frame at the designated mounting position.

Important considerations:

Mitering required: The boss must be mitered (angled) to match the seatstay or fork leg geometry for proper fit and a clean weld joint
Ensure proper alignment before welding — brake bosses must be parallel and positioned correctly for proper brake function
Use appropriate heat control to maintain material properties
Post-weld cleaning recommended for cosmetic finish

Compatibility

These brake bosses are compatible with all standard cantilever and V-brake systems that use M10 x 1.25 threaded mounting studs. Always verify the specific requirements of your chosen brake system before ordering.
