Shimano - XTR SM-RT99 Disc Rotor
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°C. When used with Ice-Tech pads surface temperatures can drop from around 400 to 300°C, this Shimano disc rotor provides great improvements in braking performance.
Features:
FREEZA rotors allow the alloy core to extend out from the braking surface as a fin to providing added cooling
Ice-Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion
Rotors are durable lightweight and rigid, using the proven Shimano centre lock system giving increased strength and security with an easy set-up
Precision cut and drilled braking surface improves pad clearing in muddy conditions while aiding cooling under high load
Large alloy spider is a highly rigid and lightweight support for the rotor surface
Super polished braking surface gives excellent braking performance
Please Note: 140mm rotor is for rear brake use only
