    8 speed to 9 speed

    If I change to that, will the 9 speed cassette be to wide to where I would have to change the hub perhaps? Or something else... other than the shifters.

    I hade the same question and called my lbs. They said I need a new shifter, derailer and cassett. Then the guy told me I don't really need 1 more speed, that I would never know the difference. Once I thought about it, he was right (just saved about $225).
    If it works...... do it!

    The hubs are the same, but you would have to change the chain, rear derraileur, and shifter, which you know.

    Yeah, there is no need for 9, the high and low will still be the same, just closer ratios. Its a scam to get people to buy parts they don't need.

    to go from 8 to 9 you will need the following new parts:

    - 9-speed cassette
    - 9-speed rear shifter compatible with your existing derailleur
    - 9-speed chain (narrower than 8-speed)

    If you are already replacing worn out or broken parts and you REALLY want the extra cog, then go for it. That said, I'm also of the opinion that your $$ can be much better spent on parts other than those above if you are considering going from 8 to 9 speeds just because. Keep the parts you have and if you find yourself wanting a gear higher than one and lower than another, shift into the higher one and push a bit harder.

    A new derailleur is only necessary if you're switch actuation type (rapid rise or SRAM 1:1).

    For some reason, they don't like making 12-34, 11-34 cassettes in 8 speed. They only make those "Mega-Range" cassettes. I'm not sure if it's a shifting interval thing or just marketing.

    I'm sticking with 8 speed. But if I build a new bike, it will be nine speed.

    The main reason I upgraded was due to the fact that I had hand-me-down parts left over from bumping up the component spec on my trailbike
