I am thinking of upgrading after all these years. I want to take my old
Gary Fisher Jashua from 8 to 9 speed. I got a new XT derailure about three
years ago, so that should work with 9. The hub should take a 9 speed
cassette. What I am not sure of is, will an 8 speed XT mountain crank work
with a 9 speed chain? I've been told it can fall between the rings when you
shift and get stuck due to the more narrow 9 speed chain and the larger ring
spacing of the 8 speed crank.

Any thoughts out there?

Thanks, Dave
