SM-RT81 Ice-Tec rotors give excellent performance and are 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.
Brake disc rotors are available in many sizes and fitments. Wiggle stock a range from 140mm up to the largest which are 203mm. Fitment varies from IS (International Standard) 6 bolt to Shimano's new Centre Lock splined type. Wiggle also hold some of the older rotors made by Hope and used by Cannondale, such as the 4 bolt Coda and 5 bolt systems. It's common for rotors to be different sizes from front to rear, with the front usually having a rotor one size up from the rear for brake bias balance, 185/165mm for example. This is because when braking, your weight shifts to the front of the bike and as much as 75% of the braking is on the front, with the rear used for control.
