I have been experiencing some issues with my rear derailleur. I played around with it quite a bit to adjust it correctly. Finally after giving up, I took it to the shop and the guy showed me that the rear derailleur is bent, plus the chain is stretched. So, I am considering changing it along with the chain.
I need some recommendations, not necessarily on the exact model, but the type of derailleurs. The person at the shop recommended Shimano Deore. But I noticed that these seem to be for mountain bikes. My bike is more of a hybrid (if that is what it is called) La pierre Shaper 100.
Would regular road bike derailleur's work? I use the bike mainly for commute (36kms/20miles daily).
Would really welcome suggestions, thoughts, etc?
Edit. Down the line I might consider changing the rear cassette from 8 to 9, or maybe 10, will the front derailleur have to match up with the new cassette at the back and the new rear derailleur to make sure each gear in the front has a big enough range for gears at the back without the chain touching the front derailleur?
