    It won't shift well, unless you put a 9 speed cassette on the pt wheel. If you just leave it in 1 gear for warming up, that might be ok as long as the wider 9 speed chain is ok on the narrower 10 speed cassette. try it and see

    I don't think it will set on the cog. Isn't the 9 sp chain width wider than the cog spacing on a 10 sp cassette?
