So my lbs was building up the bike this morning and the 2x10 front derailleur has clearance problems. If i mount it below the lower bottle boss, then that is too low...above the boss and it's too high. Apparently there is another version of the dérailleur and that part is on order. Can anyone confirm that the lower mount top pull dérailleur will work? All parts are XTR 2x10. The crankset is 38x26...would the M985 low clamp do the job?
