    can anybody tell me the bottom bracket size for a 650 606???

    trying to see if my Shimano Deore XT FC-M770 Crankset will fit this frame.... any advice on this would be awesome!

    KHS does not lists the specs, but I'm guessing it's 73MM only since my 2 KHS models are. Either way, the M770 can do 68mm or 73mm and should work fine. For 68mm you need 3 spacers (2 on the drive side, 1 the non-drive side), for 73mm 1 spacer (on the drive side). I would double check this with the Shimano tech docs as I used the doc from my M532 with Hollowtech BB so it should be the same.
