Make sure that chop stops in style. Designed for a 3/4" axle and 10" rotor this bracket is a clean way to mount a GMA "B" style caliper* to many springer front ends. I personally run this mount on my bike "Bad Juju." 304 stainless steel and 3/8" thick run it raw or polish it to a shine. This is non-axle bushing version of this bracket. Always made in the USA.
