9 speed chain on 10 speed cassette ?
While digging through a couple bins of spare parts, I found I have several Shimano 9 sp chains left over from years ago, and a new 10 sp cassette, that I got for a future service my current road bike (I installed a new KMC 10-sp chain last year, soon after snagging this bike on Criagslist, but will be looking to replace both the cassette and chain at the end of this year.)
I tried Googling the question, and though i found info saying Shimano's 9, 10 and 11 sp stuff are interchangeable, I didn't find a direct answer to my question, and I suspect the wider 9sp chain will be somewhere between "less than ideal", to "completely incompatible".
Any good info is much appreciated.....
