I would chose a Shimano Deore rear derailleur, they are 9spd, but 8spd works just fine with it, lots of people do that. I plan on upgrading my Sirrus to a Deore rear derailleur someday myself, and its 8 speed. Or you could get a shimano Alivio rear derailleur, Should work fine unless your friend plans on offroading: http://www.jensonusa.com/store/produ...erailleur.aspx
Or, if your friend likes gripshift, here are more SRAM made, shimano compatible shifters, http://www.jensonusa.com/store/produ...p+Shifter.aspx you would have to buy an 8 speed rear and index or "microfriction" front. I would go with the microfriction front if gripshift are ok, it lets you trim your front derailleur so you just about never get chain rub!
I link to Jensonusa becaus I deal with them a LOT, and seem to always get decent prices there. E-bay is another choice, but especially shifters, why ebay if you can buy brand new gripshifters for $20 or less from a reputable dealer? I would try to find a DEORE rear derailleur on ebay though, Cant seem to find many online right now, from the dealers I check at least.
Good luck, and you sound like one heck of a friend
ah thx for the advice im going to go those shifters you suggested and that probably that Alivio rear derailleur
I also have these front derailleurs which i might replace that stx-rc one with:
shimano xtr fd-m952
shimano deore lx fd-m563
Those front derailleurs might not fit that bike, the frame looks to be a bottom pull cable routing, and most lx and xtr front derailleurs I have seen are top pull. If the stx-rc is in good shape, I would leave it be. Probably works just fine!
the front deore is bottom pull
thx for all the help man
anytime! I love fixing bikes, it is a lot of fun for me. I wish there was more money in it, but I have thought about putting an ad in craigslist come late winter, offer good prices on tune up/overhauls. Shops charge $150 here for an overhaul, I could charge $80 and still make money off it. By make money, I mean buy some more and better quality tools
Again, good of you to help a friend out. I built a bike up for my brother using a new frame he paid for and a whole parts group off a bike I had the frame crack on. Told him if he bought the frame and chain I would give him all the parts...he ended up giving me $50 extra so I gave him the better condition wheelset I had. He now has a bike he would have had to pay $400+ for in a bike shop, for only $200 And I made some room in our basement...
