    HammerSchmidt with internal hub gear

    Has anyone tried using a HammerSchmidt with a nexus 8 speed internal hub gear?
    Im thinking of doing it and was wandering if anyone else has already.

    You still definitely need some sort of spring loaded chain tensioner to accmodate frame movement, but an externally simpler drivetrain would be very cool IMO. ;^)

    Will a Nexus hub even hold up to real off road riding? I thought that was more for comfort bikes and such. Rohloff works, but costs as much as the HS (or more....)

    Some internal gear hubs including the SRAM and Rohloff have limitations for the input gearing to limit maximum torque.

    The Hammerschmidt's low gear is a 1:1 drive with a 22 or 24t chainring.

    The lowest input gearing Rohloff allows for the 14 speed hub is 2.375:1 - that means with a 22t Hammerschmidt, you would have to run a 9t cog or smaller, or you lose your warranty.
    With SRAM hubs, it seems to be either 1.75:1 or 2:1, so you'd have to run 11t cog on the hub if you want to combine it with the Hammerschmidt.
    Not sure if Shimano has published a limit.

    the alfine will do fine. it will take the pounding. I am currently using one on my xc bike, but that same hub was on a Dh rig for over a year and it never gave me a problem.
