I am looking to replace my crankset, and am thinking of going to a 1x9 setup. I like the Saint 810-1 or 815-1 but am confused why they are the same price as the -2's, but don't even come witht he chainring or bashguard? Which is an extra $120-150. For the cost, it seems that may be better off just going with an XT and converting. Any thoughts?
