I'm looking for a 9-speed front derailleur, top pull, that can handle a 52-38-26 setup. On an 8 speed, I got this type of crank setup working with an old XTR FD-M901 (and a 105 SC rear with 12-21 cassette). Yeah, it's going outside of it's spec of 22T capacity, 48T max, but it actaully worked pretty well. Then my bike got stolen So I'm building a better one, with 9 speed this time. Has anyone tried someting similar on a 9 speed setup? If the new 9 speed FDs just cant handle going outside of spec, what'll happen if I try to use the M901 with a 9 speed crank and chain? Thanks.
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
I'm using that gearing range on a 9-speed Ultegra crank with 52/42/26 chainrings and a 105 9-speed triple fd and it works just fine. However the 105 is a bottom pull (as are almost all road fds) so I don't know what top pull derailleur will work.
