AC Front Derailleur and Bottom Bracket Sizes
Could someone verify these figures for an AC:
Front Derailleur = 34.9mm (1 3/8") Top pull, top swing
Bottom Bracket = 68 x 113
I would like to reuse my current front derailleur and bottom bracket from my NRS but I'm at work , so I can't exactly go and take a look at derailleur. As for the bottom bracket, if anyone knows if the Shimano BBES-71 (68 x 113) will work with a 2003 AC, I'd really appreciate it.
(...only 3 more hours of work.)
C'mon...someone must know this.
Yes the BB will work with XT cranks or the old LX (M571?), but not the newer M572.

For anyone that might be interested, the vitals are:
Front derailluer = 34.9mm or 1 3/8" Top pull w/Bottom Swing
Bottom Bracket = 68mm x 113 (that's based on a '03 XT...the newer LX will need a 68mm x 121 BB)
Seat post = 27.2mm shimmed to a 30.8mm...or just spend the $$$ for a 30.9mm Thomson
Headset = INTERNAL...e.g. Cane Creek ZS 2 or 6
