    9 speed upgrade

    Would a 9speed hub work on a 2009 19" specialized hardrock disc? it came stock with a 7speed hub.

    By 9 speed hub I assume you mean a 9 speed cassette. If so then it won't work. I have a 19" 2009 Hardrock. The stock 7 speed cassette uses a freewheel design hub. To use a 9 speed cassette you need a rear wheel with a freehub design.

    Nope, you're stuck with 7 speed, even though the spacing is the same for 7,8,9, and now 10.

    I upgraded my Hardrock to a 9 speed drivetrain. Trust me it doesn't come cheap. At the very minimum you will need a new rear wheel (you could get away with buying a new hub but you will have to have the rear wheel disassembled and re-laced with the new hub, not worth the effort), 9 speed cassette, 9 speed rear shifter, and a new chain (the 7 speed chain is wider than a 9 speed chain)

    You might also need a new rear derailleur and crankset depending on what you are currently using but I am not 100% sure on that.

    Im plannin on changin all that stuff. right now im tryin to find a good R wheel. I snapped the axle on the stock R hub. I was looking at the spin doctor hubs since they come in a freewheel version. now its just finding a wheel/hub thats compatable. Im not to worried about the upgrade to 9 speed 7 speed is fine. Most of the parts im finding say 8/9 speed compatable, not even listing 7 speed.

    So i can convert my bike 9 speed i just have to find a 9speed freewheel hub/wheel/chain?

    I don't think I've ever seen a 9 speed freewheel. I think 7 speed is the highest freewheel you can find. Good luck though.

    how did you you upgrade your 19" hardrock to a 9 speed if they dont make freewheel hubs in 9 speeds? you said that the 19" hardrocks only work with a freewheel hub..

    What wheel did you buy when you made the upgrade to 9sp? did you get it put together custom?

    Thanks

    You can buy a hub that accepts 9 speed cassettes, it just won't be a freewheel hub.

    I bought new wheels with a freehub design in the rear that accepts a 9 speed cassette. Here is a link to the wheels I bought.

    No problem, if you need any help with future upgrades just drop me a PM. The only original part on my Hardrock is the frame so I have some experience with the bike

    I just bought a Hardrock sport 29". It has an 8 speed casette. My only problem with it is that it's got a 32tooth largest cog. I just upgraded my 26" bike to 9speed rear by buying wheels/ cassette/shifters(and derailleur for a nice matching set) Wheel world in Culver City has great prices on these components. As soon as the "New bike Smell" comes off my Hardrock 29 I'll do a similar upgrade but wondering about a 11-36 (or even 11-38?) cassette.
