With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Shimano RT-CL900 Ice Tech FREEZA rotor with external lockring - 140 mm

Season:All Year Round

Code:RTCL900SSE

The Shimano RT-CL900 Ice Tech FREEZA rotor represents the pinnacle of braking performance for road and mountain riders seeking precise control and consistent stopping power.

Designed at Dura-Ace and XTR level, this rotor uses Shimano’s revolutionary Ice Tech FREEZA technology — a 3-layer stainless steel and alloy construction that rapidly dissipates heat, reducing surface temperatures by up to 50°C for fade-free performance. The finned alloy core extends beyond the braking surface to enhance cooling further, while the large alloy spider provides lightweight rigidity. With the Center Lock system for quick installation and a precision-polished braking surface, the RT-CL900 ensures smooth, quiet, and reliable braking in all conditions.

  • Improved heat dispersion ensures longer pad life, quieter operation, and reduced brake fade
  • Durable, lightweight, and rigid design using Shimano’s proven Center Lock system for secure and easy installation
  • Precision cut braking surface enhances pad clearing and cooling under heavy braking loads
  • Large alloy spider provides stiffness and weight savings
  • Super-polished braking surface delivers exceptional smoothness and control
