I adjusted my front derailleur and now it seens that my rear derailleur is hitting my spokes when I am in 39/27, it makes contact with a about 2 to 3 spokes so that i cant be on 39/27.. it might be making me a stronger riders but I try to adjust and nothing help,, Any ideas plaese????

Check your deraileur hanger. It doesn't take much to bend it, especially if you lay the bike down.

I agree with Atombomber, I suspect your derailleur hanger is bent. I'd get it fixed real soon too, before you twist your derailleur cage into your back wheel.

I had this problem, when my rear der was worn out. The whole thing became very loose and would move in towards the spokes under heavy load. This was after about 5,000 miles in all weather!

most likely its your hanger being bent, but there's also a chance that it is simply out of adjustment. If you touched it at all you could have thrown it off. Most shops won't charge more than ten bucks for the adjustment and they'll be able to tell you if it is a bent hanger too.

Spoke contact in the lowest gear (and not throwing the chain) usually indactes a bent der. hanger and/or bent der. Park sells the tool (DAG-1) for around $50, but you're probably better off paying less ($10 to $15) at the shop instead of buying the tool - it isn't something that you use everyday. Do enough work on bikes and owning one becomes essential.

If the situation is allowed to continue it'll cost you more than $50 and will suddenly end your ride.

I was going down a sttep hill about 40 mph and at the botton I when from 53 to 39 ( I know dummmm)and the chain came off the ring,,I realise it right away I stop and put it back and then the problems started,,I guess i should just take to the shop..

...shouldn't really cause any problems. Unless something strange happened.

Something that may be worth considering: If you increased the size of your largest cog and you didn't make the chain longer you can really tweak things if you shift into big/big, apply power, and have the drive train lockup.

All of this is speculation, but it's the best I can come up with. Ultimately you need someone with some experience and the correct tools to look at it.

You just saved yourself some time and $$$ vs. the LBS. Plus you learned something that you can use. Bikes aren't rocket science, mostly they just take patience and curiousity.
