Thanks for the offer, but I am now stocked up for an estimated 3-4 years of wear and tear. Went on a small buying spree. FD, RD, chainrings, cassettes, BBs. Everything XT and on sale!. I already had a partial stash-I tend to pick up stuff as it comes on sale for later use.
Thinking about the change from 9sp to 10sp there is really no benefit that I can see for those of us with triple cranks. I mean the gear range is actually less compared to a 9sp with the lower high gear (low gear remains the same). Weight is a tad higher and the cranks are the same design. But not to worry. Everthing 10sp is more expensive.
At least when they went from 8sp to 9sp, there was some real advantages such as going from square taper BBs to pipe billet (octalink) which really stiffened up the cranks and going from a 30t low to a 34t low for XT on the cogs. Plus they beefed up everthing without much of a weight gain
