SM-RT81 Ice-Tec rotors give excellent performance made from a stainless steel / alloy 3-layer sandwich construction that manages heat while riding
The clad steel / alloy / steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 deg C.
When used with Ice-Tec pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all round
Ice-Tec rotors achieve long pad life, less noise and less fade due to improved heat dispersion
Shimano Centre-Lock system provides excellent rigidity and security with an easy set-up
Rotor contact surface has been developed for excellent pad clearing and cooling which increases pad performance and life
Large forged alloy spider supports rotor surface, increasing rigidity and reducing weight
Comes complete with alloy lockring
160mm rotor
Weight - 130g including lockring for 160mm rotor.

Just got these XT SM-RT81 brake discs from Total Cycling, Ihave them in several bikes and I feel they're the sweet spot in the quality/price balance, really topnotch, high-end and great looking discs. Total Cycling price and service were great, delivery to my home at Orlando, Florida, USA, was amazingly fast, very recommended!
