If you wish to upgrade your brake rotor, look no further. These are the best that money can buy. Perfect braking power, heat management, looks and durability!

Coupled up with a pair of ice tech pads, braking with this rotor is genuinely silent and powerful. On the other hand this rotor is consumable. Due to its triple layer 'sandwich' construction, after an extended period of use this rotor becomes thinner and can no longer be used as the two outer layers deter. However, this has not put me off at all from purchasing a second pair of these top noch rotors because of their superb braking power, strength, durability and absence of irritating squeaking sounds.

This 203mm disc lasted 5 years. Breaking power with SLX resin pads is plenty for hard trails and xc. However, the aluminium core MELTED suddenly and the brake system failed during a long descent in the alps. This is a design flaw or limitation nothing more. Replaced with SM-RT99.
