Shimano Flat-Mount Road Disc Caliper Fixing Bolt C

The Shimano Flat-Mount Disc Caliper Fixing Bolt is specifically designed to work with Shimano flat-mount disc brake calipers, which are commonly found on road and gravel bikes.

The fixing bolt itself is made up of two main parts: the threaded bolt and the mounting bracket. The threaded bolt is usually made of steel and is threaded on one end to screw into the frame or fork. The other end of the bolt is typically a hex head that is used to tighten or loosen the bolt.

The mounting bracket is usually made of aluminum and is attached to the caliper. The bracket has two holes that align with the threaded holes on the frame or fork. When the bolt is threaded into the bracket, the caliper is secured to the frame or fork.

It's important to note that there are different sizes of fixing bolts available, depending on the frame or fork and caliper compatibility. Shimano typically provides the necessary bolts with their brake systems, but if you need to replace a bolt, make sure to use the correct size and thread pitch to avoid damaging the frame or fork.

Additionally, it's important to use the correct torque specification when tightening the fixing bolt. Over-tightening the bolt can damage the frame or fork, while under-tightening can result in a loose caliper that can affect brake performance.
