New chain, rebuilt rear derailer, and now problems
So I tore apart my rear derailer, an old Shimano Altus, thoroughly cleaned it, lubes with light oil and reassembled it. Works great...
I got a new chain and popped it on.
Now it seems I'm having trouble. The chain movement is not smooth. It's sort of clicking and jumpy, and it might ocasionally skip a tooth. I checked and the links (old vs new) look pretty much the same size. Also both chains have the same number of links. Could it be that the chain will stretch over time to accomopdate the small amount of slack present?
Also, i seem to be having chain alignment issues. With the front derailer all the way 'slack', I still get the chain rubbing the innermost surface (left side when looking sown riding the bike) when on the small chainring. The adjustement screw is all the way out. My hypothesis is that I've got too much tension in tghe shifter cable. (friction shifters). Could this be the case?
