The SM-RT70 brake rotor for SLX by Shimano - lockring with external toothing


This Shimano SM-RT70 Center-Lock brake rotor is, unlike earlier models, equiped with an externally toothed lockring. The ingenious Ice-Technology, a sandwich composite of two layers of stainless steel with an inner layer of aluminium, has been known for a long time. Even on long descents and difficult trails, this rotor ensures excellent heat dissipation. The SM-RT70 rotor is recommended for newer SLX brakes, but is also compatible with other models.

verified purchase
item: silver/203 mm

Got his on sale and bought them before the new bike with BR-MT410 calipers came in. While assembling the bike I replaced stock 160/180mm rotors with two of these and of course appropriate PM adapters.
After 500km of flawless performance a friend warned me that these are for narrow pads. Indeed that's what he specs say but the rotors work really well for me and the wear on rotors suggests they can handle wider brake pads just as good.
