Construction
Ice Technologies steel/aluminium/steel
The Shimano SM-RT70 is a Centre Lock disc rotor from the SLX family, widely used on both mountain and road bikes. This is the 140 mm version, the most common rear rotor size on disc road and gravel bikes.
Its braking track uses Shimano's Ice Technologies construction, an aluminium core clad in stainless steel. Aluminium sheds heat far faster than steel, so the rotor runs cooler under long or repeated braking, which means more consistent feel and less fade.
Centre Lock makes fitting quick: the rotor slides onto the splined hub and is held with a single lockring, with no six-bolt pattern to torque up.
Road and gravel riders with Centre Lock hubs who want a cooler-running, quality 140 mm rotor.
