that popping noise reviewer mentioned is chainsuck from the driving face of chainring teeth lifting the chain rollers as the chain leaves the ring to go to the rear mech. it is due to the square profile of the teeth, and as the reviewer wears the ring more it will trangess to all the other cassette cogs. this is a major flaw and can be remedied by filing off the square front corner of the c/ring teeth. my c/ring is a bit more worn than the one in this pic and is unrideable when under any load.and its only 30 hours old. not impressed.i have had xx1 for 5 months, ride 3-4 times a week, have only had 6 wet rides, always stay seated when climbing and am on my 3rd chainring already yet chain is only at 50% wear
