  • Our take on the Shimano Flat-Mount Road Disc Caliper Fixing Bolt B

    A single replacement mounting bolt for Shimano flat-mount disc brake calipers. It is a small service part, not an upgrade: you buy it when a bolt is lost, stripped or corroded. It fits flat-mount calipers that use this bolt type, so check your caliper model and bolt length before ordering. Generic hardware-store bolts can work, but this one matches Shimano's thread and head spec.

    Will this fit my flat-mount caliper?
    It fits Shimano flat-mount calipers that take this bolt type. Check your caliper model and the length of the bolt you are replacing before ordering.
    How many bolts do I get?
