    Hello,

    I asked about this a few months ago, now I can't find it and I was wondering if someone could help me.

    I am looking for an axle that will accept a sprocket/cassette on both sides thus eliminating the need for rag joints and other methods for getting the chain driven sprocket attached to the rear wheel.

    Thanks!

    This is what was suggested to me, but I dunno about it.

    Its just the hub, so by the time you add in the rims, spokes, lacing, sprockets/freewheel you might as well get a shift kit for the money. But I am torn about that too. A shift kit is about 150 bucks, and I just don't know if it's worth it. I bought a clamshell sprocket adapter from creative engineering and it is ok, but it likes to roll on the axle. What I am trying to say is that it rotates on the part it is clamping onto. When it does that, it breakes off spokes. I tried to put a set screw in it, but that's not holding either. The original rag joint isnt an option at all for me, so I am trying to find a better solution to get the power to the wheel. Any Suggestions?

    If the adapter is spinning on your hub that means you got the wrong size. It's most likely that you might of measured it wrong.

    There are cheaper hubs to be found on Ebay. One or more venders are known to sell both freewheel and non-freewheel hubs with brakes. The left side sprocket is included and the right side is threaded for single or cassett sprocket(s).

    I doubt that. I measure crankshafts for a living to the .0001"

    I think I know how to use a micrometer.

    Besides, I am not saying I am displeased with the adapter, it's just not perfect. There needs to be something machined into the I.D. to prevent slip. Something like a series of grooves, or bumps or something. A smooth surface WILL rotate across another smooth surface, unless there is something there to stop it. No matter how tight you get it, thermal expansion will cause the steel of the hub and the aluminum of the adapter to expand at different rates and widen the gap enough to make it loose enough to spin.

    TJS323626, Please drop me a link to the other hubs you have found. I would love to check them out. I am open to all suggestions.
