    8 spd to 9 spd new der.

    I just read in the raod bike forum that you do not need a new deraller if converting from 8 speed to 9 speed.how true is this?

    That's true. But let's also asssume you are talking shimano and the 8 speed RD is not Dura Ace.And also that the 8 speed unit is not wore out or sloppy.

    Think about it a little. The rear derailleur guides the chain from the middle so it doesn't care.

    The front derailleur guides the chain from the sides. 9-speed front derailleurs are a tiny bit narrower than 8-speed. I'm told the difference isn't a problem for double chainring conversions but I've found it necessary to use a 9-speed front derailleur when converting a triple.

    no, i was just trying to get info from more than one source. my thought was that a 9 speed chain may not run thru the pullys properly, being that it is a hair smaller.

    I did not mean to offend anybody just wanted a second opinion.

    Take a good look at your pulleys.
