Shimano Rotors and Rotor Hardware

- (IS): 6-bolt/44mmBCD International Standard, (CL) 35mm CenterLock spline-mount
- All rotors include hardware: either 6-bolt or CenterLock lockring+washer (lockrings for thru-axle applications available separately)
- RT99 Centerlock rotor optimized for pure gravity. Takes the innovative 3-layer clad rotor to the next level by adding radiator fins. Braking and performance benefits include 20% less brake fade, 20% increase in stopping power and 20% longer pad life
- RT98 CenterLock rotors are for XTR applications and utilize a bonded steel-over-aluminum "Ice Tech" design with an aluminum spider/carrier for decreased weight and improved heat dissipation (replacing RT97/96 versions)
- RT76 6-bolt rotors can be used with all Shimano disc brake systems: XTR,Saint,XT,SLX,LX,Deore,etc. (note: the newer RT76 rotor uses a lightweight 2-piece design with a 5-arm aluminum carrier and a stainless steel rotor)
- CenterLock lockring/washer applications: (QR) for quick-release hubs, (TA) for thru-axle, and (F or R) for front or rear when applicable
