  – Shimano / FSA MegaExo: 24mm
  – SRAM GXP: 22/24mm
  – Campagnolo Ultra Torque: 25mm
  – BB30: 30mm

How to Find the Right Ceramic Jockey Wheels

Follow these three steps to choose the correct jockey wheel product for your bike:

🔹 Step 1: Identify Your Rear Derailleur Brand and Model

• Common brands include:
  ▪️ Shimano
  ▪️ SRAM
  ▪️ Campagnolo

• Check the model series and speed (e.g. 10-speed, 11-speed, 12-speed).
  – Example: Shimano Ultegra 11-speed, SRAM Eagle 12-speed, Campagnolo 11-speed

🔹 Step 2: Confirm Pulley Wheel Size/Tooth

• Most derailleurs use standard 11-Tooth pulley wheels.
• Some models (especially SRAM Eagle or XX1) use oversized pulleys like 12T+12T or 12T+14T.
• You can use oversized jockey wheels on your current 11-tooth system. All the oversized options listed here (12T and above) are compatible with medium cage derailleurs without needing to change the cage.
• Up to 13T+15T options can also be installed without modifying your cage or chain length.

🔹 Step 3: Match and Click

• Use the jockey wheel compatibility chart below.

• Click the product link that matches your derailleur model and speed.
