After purchasing my first Blackspire chainring, a 32t middle ring , I've been a real fan. The Blackspire stuff isn't the lightest, but the quality is there and the stuff is tough.
The 22t Super Pro chainring is no exception. Its weighs 28g on the scale, which is about 8g more than a stock XT 22t chainring, but the extra weight is well worth it for the piece of mind. There's lots of force involved when you're cranking a 24t front, 34t rear up an almost unrideable slope.
