Know before you buy

Yes, the Shimano RT86 6-bolt rotor includes the required mounting bolts and locking plates for a secure installation.
The RT86 is built for high-performance demands and offers excellent heat dissipation, making it a reliable choice for technical trails. However, if you frequently ride steep, long descents, you may want to consider if your frame supports a larger rotor size for increased thermal capacity.
