Bit off more than I could chew
Oh, I have done it again. I am always turning routine repairs into such ordeals. What I am trying to do is replace the crankset. I have a Shimano Alivio, which I am replacing with the same make, but I just can't get the derailleur lined up to work.
FYI...this is unrelated to my earlier problem concerning derailleur placement. I haven't even starting working on that one yet.
The problem with the Alivio is that the chain won't stay on the second chainring. It slips back onto the first one. When it is in first gear it seems as if the angle is too sharp for the chain to stay on the 2nd chainring, but it works fine with the old crankset. I do not know what else I can adjust to rectify this. Since it is the identical crankset I would not think there would be too much difference.
Any suggestions?
