About this product
The Shimano Flat-Mount Disc Caliper Fixing Bolt is a precision hardware component used to secure Shimano flat-mount disc brake calipers to compatible frames, forks, or flat-mount adapters. It ensures correct caliper positioning and secure installation within Shimano’s flat-mount braking system.
Flat-mount systems rely on specific bolt lengths and configurations depending on rotor size and whether the caliper is being mounted to a frame, fork, or adapter. These bolts are engineered to provide secure clamping force while maintaining proper caliper alignment over the rotor.
Correct installation torque is essential to ensure safe braking performance. Over-tightening can damage frame or fork threads, while under-tightening may result in caliper movement and reduced braking efficiency.
Key Features
- Flat-Mount System Compatibility – Designed for Shimano road and gravel disc brake caliper mounting standards
- Precision Length Variants – Specific bolt lengths used depending on frame, fork, and rotor configuration
- Secure Torque-Controlled Installation – Ensures safe, stable caliper alignment under braking loads
