Know before you buy
The Centerlock system uses a splined interface and a lockring, which allows for faster, more precise installation and removal compared to traditional six-bolt rotors. It also ensures a more secure fit, reducing the risk of bolts loosening over time.
Your frame and fork have specific maximum rotor size limits, so check your manufacturer's specifications first. Generally, larger rotors like 180mm or 203mm provide more stopping power and heat dissipation for aggressive trail riding, while 140mm or 160mm are sufficient for cross-country or road use.
The RT70 is compatible with most Shimano disc brake systems that utilize Centerlock hubs. However, you should ensure your brake pads are compatible with the rotor's braking track width and material to maintain optimal performance.
While the Centerlock mounting is a standard interface, the rotor's braking track is optimized for Shimano brake pads. You can use it with other brands, but you may experience variations in noise, wear, or braking feel depending on the pad compound.
Yes, the Shimano SLX RT70 typically includes the necessary lockring for installation. Ensure you have the appropriate external or internal splined tool to tighten it to the manufacturer's torque specifications.
