Review by Michigan rider
There is a significant difference in lifespan for the X01 chains vs the GX chains. I don't find much of a performance difference in the X01 shifter or derailleur and the weight savings are negligible, but the X01 chains and cassettes are worth the cost of upgrading based on lifespan alone.

This chain may be slightly heavier than others but it can handle tough racing abuse. Durability wins out with this chain!
