Sorry to the OP for the slight hijack - but I'm about to go through something similar, if not exactly the same.
I'm planning a mish mash of parts. M730 cranks with old middleburn big ring, new 9 speed compatible middle ring, old shimano granny ring. Mechs will be M739 front and rear, shifted with dura ace / Pauls thumbies. Cassette and chain will be SRAM 9 speed.
Can anyone see any massive problems with this lot ?? ^^
Logic tells me that backing off the limit screws on the rear mech will allow it to work on 9 speed, and that the only issues *may* be with the front chainrings being fat - but I guess I won't know until I try
Am I missing something ? Any advice appreciated....
It's not about getting what you want, it's about wanting what you've got.
