    New question here. Sram I-motion 9 Internal Geared Hub?

    Anyone have any information on WHERE to BUY an I-Motion 9 Non-Brake Hub NOW?, i have searched, no one has one in Stock nor has any anticipation of getting one anytime soon, a US or EURO Purchase is fine...... ideas? THANKS!

    A Google search of German sites brings up a few retailers who *appear* to have them in stock (I don't read German, and they don't translate to English).

    Get an Alfine while you can, who knows when there'll be more IM9s here in the US. I made a spreadsheet with gear inch charts for the Alfine vs IM9. The only real difference is that the IM9 has an extra high gear. The IM9 is constrained to a primary gear between 1.7 and 1.9, this sets the range.

    IM9 with 1.7 primary gear (34/20) gives a range from 27 inches to 90 inches.
    Alfine with 1.7 primary gear (34/20) gives a range from 26 gear inches to 80 gear inches

    IM9 with 1.9 primary gear (34/20) gives a range from 30 inches to 102 inches.
    Alfine with 1.9 primary gear (38/20) gives a range from 29 gear inches to 89 gear inches

    These are the limits set by the SRAM with 29er wheels. I don't know what Shimano's limits are.

    Alfine has thumb shifter, IM9 only has grip shift. Alfine w/shifter cost $250, IM9 w/shifter cost $450. That's a big difference in price for an extra high gear, esp since a MTB doesn't have much use for the extra high gear. I've purchased both the IM9 and the Alfine, I'm going to give both a try and decide which one shifts better. If the Alfine shifts better too...I might have an IM9 to sell

    Thanks for the Alfine info - i would try to buy either HUB for my build - where did YOU get your Alfine? ...also - is there much weight difference between the Sram and Alfine hubs and did you happen to check them? i can not find weights on EITHER HUB.
