over the summer i bought a 99 schwinn le tour for $100. it all appeared to be in great condition and it worked fine for a few months. then about 2 weeks ago the whole deraillure(sp?) got all bent out of shape. so a friend of mine recommended i just strip it all off and make it fixed. so we did and all was well again... until the quick release rear kept slipping. every time that happened i broke a link. so i just dealt with it and bought a chain tool and figured it was no biggie. then yesterday it slipped for the last time and the qr skewer was stripped beyond use. 2 local shops said i just need to eat my wheaties and muscle the new skewer i bought for temporary riding, on there, but i think that was my problem since it was all stripped and such. so in short, i think it would be best if i actually purchased an entire new rear wheel meant for riding fixed since i have been using my old 7 cog stock wheel with the qr problems. what would the general recommendation be? i dont want to spend so much that i would regret not just buying a new bike, but i dont want to have issues with cheap crappy parts that wont last me.
