SRAM XX SL, XX and X0 Eagle Transmission (T-Type) Cranksets are available in different Q-Factors (168 mm and 174 mm). The chainrings that fit these cranks come in both 0 mm and 3 mm offsets in order to fit both Boost (52 mm chainline) and Wide (55 mm chainline) bikes. Therefore, you need to be sure you order the correct chainring offset based on your cranks’ Q-Factor as well as your chainline. So we put together the following information to make it as easy as possible!
How to Determine Your Chainring Offset
For 168 mm Q-Factor cranks:
- If your bike has a 52 mm chainline, you need a 3 mm offset chainring
- If your bike has a 55 mm chainline, you need a 0 mm offset chainring
For 174 mm (Wide) Q-Factor cranks:
- If your bike has a 52 mm chainline, unfortunately this crankset will not work with your bike and you would need a 168 mm version
- If your bike has a 55 mm chainline, you need a 3 mm offset chainring
How to Determine Your Q-Factor
If you have the SRAM X0 Eagle Transmission Crankset or the SRAM XX Eagle Transmission Crankset (Non-SL Version), your Q-Factor is 174 mm.
If you have the SRAM XX Eagle SL Transmission Crankset, your Q-Factor could either be 168 mm or 174 mm. If you are not sure what it is, we suggest sending us your SRAM part number (serial number) and we would be happy to let you know what your Q-Factor is. You can find the part number on the inside of the drive side crank arm.
