I have upgraded the Deore M591 shifters to XT M780 i-spec B and this is a step-by-step how-to, review, and comparison between the two. These shifters work with either i-spec A or B brake lever using the appropriate nut. If I am to use one word to characterize them, Deore would be smooth, XT would be crisp or precise. Bike is a 2013 Trek Fuel Ex 7.
