I need something around the 50/39 (even a 30 for a granny gear if neceessary) area (roads here are pretty much flat). I know my BB is Square Taper, but can I upgrade the crank and BB to something that isn't? Also, I don't mind the rear cassette being 8spd but I have ridden around 2000 miles with it, so if I need to upgrade it as well I have no problem with it. Also, the front derailleur can't accomodate a 9 speed drivetrain so I'd need to change that also. Any suggestions for it? The rear is fine since I know the Deore can accommodate a 9 speed cassette so I'd like to keep it. If I change to a 9 speed overall I guess that means I need to change the shifters. I really just want to change the drivetrain completely to something that is geared more aggressively for flat roads. Does anyone have any suggestions? I am in the military and stationed in Korea so going to a LBS is out of the question. I can go to the bike shop on base for installation but I have to get the parts online first. I should have just gotten the 7.5FX but I have one in the states already. Also, I'd like to do this for around $300. Thanks to anyone who replies!
