Description

This brake boss is composed of 3 pieces: a steel boss that can be welded, silver-soldered or brazed to the stays, a stainless steel ring for the brake return spring, and a steel post that threads into the boss. It is supplied unmitered and must be mitered to fit the stay by the builder. It is machined from steel bar stock. The steel post has a M10 x 1.5 external thread to fit the boss, and a M6 x 1 internal thread for the brake mounting bolt. The brake pivot on the post is 8 mm outside diameter x 16.4 mm long; all V-brakes and cantilever brakes will fit.

For pre-2008 Shimano brakes or Avid Ultimate Shorties ask us to substitute in our longer post, BK2014, as it allows 1/32" more room under the brake pivot.
