<img height="251" src="http://www.probertencyclopaedia.com/j/Derailleur.jpg" width="200" border="0" /> I have a bike that I ride for excercise now and then.  Its a Schwinn 10 speed.  As I am going up hill or pedalling hard, the chain seems to "slip" and go from one rear gear to another and its annoying and I imagine dammaging to both the chain and the gear.  Does anyone know how to fix this?  Like, what do I have to adjust?  Id rather not bring to a bike shop because I dont have a lot of $$ and Id like to try and do it myself.

<a href="http://www.sheldonbrown.com/derailer-adjustment.html" target="_self">DERAILLEUR ADJUSTMENT</a>Try this link. I used to be a bike mechanic and it sounds like your rear derailleur needs adjustment. There could also be a kink in the chain. Spin the pedals backward slowly, while paying very close attention to the links. If one or more look like they are binding up, give them a shot of lubricant. If that doesn't do it, replace the chain. After you do that, do the adjustments that the link tells you about. It's not hard once you get the hang of it.

actually, pb, i'd like to know how to know if you're putting too much strain on your chain.  i have a decent bike that's fairly new, but i have difficulty getting/ keeping the bike in 3rd.

Is this a derailleur type bike, like blackbirds, or is it a 3 speed? If it's not a 3 speed, then it's probably in need of fine tuning in the rear. Chain tension is also covered on the link I put in the last post (I think). Chain tension is a rare problem, though. It's usually adjustment that's the issue.

i have a specialized hardrock sport, 3 speed.  it seems as if i'm putting too much pressure on the chain in 3rd.  i got it last year, so it's not too old and i cleaned it regularlly after taking it off road. it's more of a feeling, but take into consideratiion, that i'm a novice.

Actually, that bike is a 24 speed. I think you're calling it 3 speed because it has 3 gears (or chainrings) in the front. Your issue is with the adjustment of the front derailleur. If by 3rd gear, you mean the largest chainring, it means you have to adjust the derailleur so that it will let the chain move to that ring easier. Don't adjust too much, though. If you do, the chain will come completely off.

Do they still make 10 speeds? I thought most of those bikes have more like 20-30 gears

Thanks for the tip! I looked at the lower gear of the deraillur(sp?) and see that it and the gears of the deraillur are out of alignment in angle to the gears on the rear wheel. (Am I using the right terminolgy?)  I just have to figure out what direction to screw in/out the adjustment screws on the deraillur to get it to line up.  By the way, the bike I am talking about is a Schwinn Le Tour 10 speed.  Probably a bit of a vintage bike, that I got in a garage sale for $20.  I have a few other bikes, the best is a late 80's mountian bike that I am sure is woefully out of date; a Ross Hi-Tec Mt Hood.  The other bike I have is one I got just to fuck around and its a Magna from Target that is more modern looking mountian bike with the hinges and shock absorbers etc. but I can tell its quality sucks and thats why it only cost about 100 new.

The Le Tour is a classic! You should be able to see the derailleur move, as you adjust it. It will take some tinkering but you'll get it. It helps if you have some way to hold the bike in the air while you're doing it. Good luck!
