7-Speed Deore LX compatibility
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?

Those shifters will definitely work in friction, and will be compatible with your rear derailer. They may not give good shifting with a 7 speed cassette/freewheel (BUT I've gone between 7 and 8 and it's always worked well for me.) If nothing else, get an 8 speed cassette and only use 7 of the cogs. If you can't find a set of 7 speed bad end shifters.

friction will work fine but i'm pretty darn sure there is a way you could get 8 speed shifters to shift a 7speed casette decently though maybe not perfectly using indexing shifters.
If i were you if your planning on using this as a commuter, I'd just leave it as a flat bar setup, its not as aerodynmaic but if your in a high traffic area it's much easier to turn around and see whats going on around and behind you the more upright you are

To the op, please read this thread, you will see that you can probably easily run 8speed indexed shifters without issues. the spacing is very similar. I used to run an 8speed setup with 9speed shifters with pretty much no issues. To the jerkoff that gives half assed answers with know it all attitude, you should read this thread then go pound sand.

First off, calm down. It looks dumb when you get all upset.
operator believes things should work perfectly in all cases. Just because you or I may have gotten it to work good enough, or even perfectly, doesn't mean it will always be that way.

The OP wants to know if the NEW shifters he's buying will be perfectly compatible with a 7 speed cogset. The answer is clearly NO. There is NO J-tek shiftmate available to correct the pull, nor is there a non standard method of changing an 8 speed shifter so that it perfectly pull 7 speed cogset spacing. You know what happens when the OP tries to index that 8s shifter onto 7?
He'll spend a month trying to adjust something that was never meant to work correctly.
Performance WILL be reduced if you can get it to shift into every gear and it will have a VERY narrow fucntional range of adjustment. Performance WILL be reduced if you can get it to shift into every gear and it will have a VERY narrow fucntional range of adjustment.

Ok, can you guys please stop arguing like a bunch of *****y five-year-olds? It doesn't really matter. Does anyone here know about an old model of bar-end shifter made specifically for 7-speed cassettes? One that would work w/ a Deore LX rear derailleur? I might just look around for that, instead of listening to you guys argue.

Thanks, now I can look around for 8-speed shifters, not just 7-speed shifters (I assume it'd be easier to find 8-speed shifters nowadays)

Oil_LOL, The only 7S bar end shifter still manufactured, AFIK is the co$tly JTEK, otherwise you're most likely to find Ultegra 8S units which will work, as everyone else wrote.
Because I have all 8S drivetrains in my little fleet plus extra 8S cassettes I changed the recently aquired 7S to 8S. To be more commuter friendly you might want to look at some 7S cassettes for closer ratios between the middle cogs.
You will have quite a nice commuter when you're finished.
