Hi. I am having issues with building a Medium 2016 EPO with XTR 980 38/26 175mm cranks. I have the BB Spacers setup correctly 1 on the driveside, but the large ring will just barely rub the metal guard on the chainstay. If I use two spacers on the driveside, the chainring no longer hits the stay, but I don't think that I am leaving enough insertion length for crank axle on the non drive side arm. Just wondering if anyone else has had issues running older shimano 2x10 on this frame or if I am just doing something stupid and/or forgetting to do something critical (probably). Thanks,
