SHIMANOSm-Rt64 Centerlock Disc Brake Rotor One Color, 180Mm

Little heavier than i expected but great stopping power on my gravel bike

This is your garden variety brake disk. It works well and came very flat and correct thickness. This is a real shimano part, so it is what the rest of the bike is designed for.Possibly important to you is the size, this is a 180mm.You can look on your existing disk and see what size you need.Gravel and road bikes may use a 160mm, you cannot use a 180mm.It may be important to not touch this with anything oily when installing, that oil can goof up your brake pads. Of course if you're all gnarly and riding in the dirt and water it might not matter much.If you're really into it you can clean it with regular household alcohol.This one includes a mounting part that requires a tool more like a BB tool, if you don't have that tool it may be a problem for you.Some bikes (sometimes gravel and usually road) come with a threaded part that uses a shimano cassette tool to install. Once again, you'll need that tool. You can re-use your old center fastener if the one that comes with the disk does not meet your needs/tool. The fastener will not wear the same way the disk does.You can measure your existing disk to see if it's worn too thin and needs to be replaced, or is bent/rubbing. If your disk is straight/flat you may need to adjust the caliper (and not replace the disk). If you ride through something oily you may need to clean your disk or just replace it. There is a torque setting on the fastener that tells you how tight to install this on your hub.

These are great rotors best bang for the buck. If you’re trying to get Shimano goodness at a reasonable price start here.

Did not come with lock rings as indicated. Component is correct otherwise.

Nice replacement for my front wheel disk brake rotor, fits well good product. No issues

These are great, and fit as advertised.

The picture shows a centerlock lockring that uses the cassette tool for installation, but the 160mm rotor actually requires a 44mm, 16 notch external BB tool.

I'm a shimano person with all my bikes. Their rotors are great and I havent had any other them ever bend too out of wack that could not be reversed after a crash or awkward hit. I only have had to replace due to being truly worn. Center lock is a plus in my book and they give you a new ring with every rotor.
