Hey all,

Just wondering...how many missing teeth mean time for a new chainring? I'm missing one at the moment on a big ring.

Second question, I've got a Deore M542 crankset. Are the higher quality sets lighter (i.e. XT) generally weaker due to being lighter?

Cheers.

One thing to consider on a Shimano chainring is that not all teeth are the same height, just be sure you're distinguishing between an actual broken tooth vs one with a low profile for shifting purposes. Otherwise time to replace when suficiently worn but on a big ring you can have a couple teeth go before you'll notice anything. Aluminum chainrings will wear faster than steel rings, but if you're asking about the actual crankset I've never had reason to doubt or even wonder about the strength of an XT set.
