A durable stainless steel rotor for riders who run resin pads and want long-lasting, predictable braking. The RT-CL300 uses Shimano's Center Lock spline mount, so fitting or swapping it takes one lock ring instead of six bolts.

Highlights

  • Center Lock mount: a spline fit and single lock ring for quick, precise installation
  • Tool-friendly lock ring: internal and external serrations suit Shimano's TL-LR11 or TL-FC36
  • Stainless steel rotor and carrier for long braking life
  • Accepts narrow and wide pad shapes

Resin pads only

Shimano designed the RT-CL300 for resin (organic) pads. Metal (sintered) pads are not compatible, so check which pads your calipers run before fitting.

Compatibility and fit

Fits Center Lock hubs, not 6-bolt hubs. Your caliper must be positioned for a 160 mm rotor, which may need a mount adapter. On E-THRU thru-axle hubs, Shimano specifies tightening this style of lock ring with the TL-FC36 rather than the TL-LR11. The RT-CL300 is also made in 180 mm and 203 mm.

Covered by Shimano's warranty against defects in materials and workmanship. Rotors are a wear item: wear, warping from impacts or overheating, and contamination are not covered. This cover is in addition to your rights under the Australian Consumer Law.

For warranty support, return the item to Tune Cycles with your proof of purchase and we'll manage the claim with the distributor for you.
