I've recently replaced the crankset on my old falcon olympic with a shimano rsx 52, 42t but the chainrings are too far from the front derailleur. I bought the crankset off of ebay and it came with a shimano un52 bb, which I currently haven't installed. If I fit the matching bb will it bring the chainrings in line with the fd or will I have to replace it? The bike currently has suntour dt shifters and a 'compe-V' front mech. If i replace the derailleur will i need to change the shifters as well? Are there any adjustments I can make to my current fd so it's further from the frame? Anybody know of any cheap and compatible fds if i do need to get a new one?
Thanks in advance!
