FAQ

What brakes is the SM-RT66 compatible with?

It pairs naturally with SLX and Deore level Shimano disc brakes, but the 6-bolt 44mm bolt circle is a standard pattern, so it works with most 6-bolt hubs and Shimano or cross-compatible calipers.

Does it work with resin and metal pads?

Yes. The SM-RT66 is rated for both resin and metal brake pads, so you can run whichever your calipers and riding call for.

Is this a 6-bolt or Center Lock rotor?

This is the 6-bolt version, which mounts with six bolts on a 44mm bolt circle. Confirm your hub is 6-bolt rather than Center Lock before ordering.

Is 160mm the right size for me?

160mm is the cross-country standard and a common rear-rotor size. Step up to 180mm where you want more braking power and heat capacity, such as a front rotor for trail riding.

Best For

Best for cross-country and gravel riders, commuters, and anyone needing a reliable, long-lasting replacement rotor at a fair price. The 160mm size is the cross-country standard and a common rear-rotor pairing on trail bikes.
