Check driver. If you have ten cogs (speeds), you will need the Shimano 10 speed driver endcaps. If you have 11 cogs (speeds), you will need the XD driver endcaps.

Front Hub

• Remove endcaps if you have not already.
• Look at bearing inside the hub and read numbers written on bearing.
• If the bearing says 6902 on it, order floating front endcaps.
• If the bearing does not say 6902 on it order standard endcaps.
