I know this has been covered here -just curious -
I just replaced my 12-26 cassette with a 12-32 (9 speed)
The 12-26 and the chain were both put on brand new at the same time about 250 miles ago.
The 12-32 came to me on a moderately used 10 year old bike.
The 6 larger cogs seem to work fine with the 53 or 39t chain ring, but neither chain ring works well on the smallest three. the smallest one works the worst, with slight improvement as you shoft down to a larger cog.
I am thinking this is obviously wear on the smaller cogs with less teeth, but could chain slack have anything to do with it? I only took about two links out of the new chain and it is not at all too tight when on the 39x32.
People riding behind me have told me the chain looks way too loose when I am in the outer section of the 12-26 cassette and the 39. I know you shouldn't cross chain, but any thoughts on how shortening the chain another link or two might affect skipping?
Btw this is a non-indexed old DT shift road bike...very small frame, so short chainstays.
Thanks for any help or thoughts.
