I recently purchased a late 90's Specialized Rockhopper Comp from someone on Craigslist. The bike is in great condition, has been sitting in his garage for ten years, hardly been used. Just a couple scratches on the chainstay (which may have been from when I jammed it in my car... maybe ). Anyway, the purpose of buying this bike was to put on drop bars, to use as a commuter. I already have the bars, and the brake levers, but now I need a set of fairly cheap bar-end shifters. I don't want to mess with Ebay and an auction, I just want to buy normally. My question is: would Shimano SL-BS64 Ultegra 8-speed bar-end shifters be compatible with a 3*7-speed Deore LX derailleur set? I assume the front one would work, but would the rear one? Also, are their any cheaper options that are nice? These are $60 on Amazon, but I would like something much cheaper. Could I find that?
