So I'll spare the full story, but essentially I was told by a mechanic while installing a front derailleur that my left shifter might be on its way out because it's not holding the cable tension required to keep the derailleur from rubbing on the extremes of the gearing combos.
My current problem is that I don't have the bank roll to make a full groupo conversion but I do have two really long organized rides coming up and of course I'd like a bike in optimal working order for both of them. So, I'm cruising craigslist and ebay and looking for the cheapest way to make a conversion from 9 to 10 speed with newish shifters. Essentially I know I'd have to have a 10 speed rear derailler, cassette, shifters and chain, but my quandry to all of you intelligent home and professional mechanics alike: Can I keep my front derailleur and crankset and will they work with a 10 speed set up? Would it be possible if the chainrings are the problem to only replace them for 10 sp specific width and save where I can?
I'm going for a second opinion on the derailleur tomorrow as it doesn't rub on the small chain ring but does on almost all gears on the large one, but am looking for a pool of information to resource. Thanks for your help ladies and germs.
