Will this RD work on my Trek 7100?
I'm a total newbie to bike repair, so go easy on me..
I need help selecting a replacement rear derailleur for my hybrid
Bought a used Trek 7100 off CL last week (circa 2003 I think) for my commuter bike
After riding it, I noticed the chain would always jump past cog #6 on the back (it would go from 5-7 each time, in each direction)
A good samaritan here on BF (bigbossman) tried fixing it and I also took it to my LBS. They said the RD is worn and needs replacing (he showed me the sloppiness in the cage compared to a new one)
I want to try and learn how to replace this myself. I've searched here on BF and Sheldon Brown's site to get some background information. So far, I *think* I'm on the right track for selecting a replacement.
But I just want to post here and make sure I'm not making any major mistakes.
Here's the RD that I found on Nasbhar, and the tech support from their website said it would work with my bike.
Nasbhar item: SH-RDC201
"Shimano C201 MegaRange SIS 8-Speed Rear Derailleur"
I examined my bike, and the front chainring (3 sprockets) is 48T/28T and the rear cassette (7 cogs) is
34T/13T (says "Megadrive")
My current rear derailleur is says "Shimano 7-speed" and has the word "Megarange" near the jockey pulley
Ok, sorry for the long novel. If you're still here, thanks.
My main questions are:
1. Is this RD compatible with my bike setup?
2. Should I get something different or better? My budget is < $35 and I'd rather get something reliable long-term
3. Are there any "gotchas" I need to be aware of (specific to my bike/RD) when replacing the RD?
