A different sprocket mount c/o Poland

[Ludwig II]

I was searching through a Polish MB site, and found a picture of a MAW engine hung on a bike. The builder didn't like rag joints and came up with a much more elegant alternative. Take a look at the pictures, the spokes fit into a spacer that fits to the original hub, and also allows a sprocket to be bolted to it.

Very nice work. So clean and simple. Thanks for sharing your find. Too bad they aren't widely available.

For mine and my friend JC's bikes, we've bolted our sprockets to disc brake rotors, but this moves the sprocket a bit further in. We're dead tight on clearance between the chain, when fitted, and the frame tube.

Until one of the specialists starts making these, anybody wanting one will have to do it the hard way and make their own.

I did some more research, and found you can get wide flange hubs. My idea is to drill and bolt directly (or with whatever spacer is required) to the flange. OK, you have to respoke the wheel, but that's an ideal opportunity to fit heavy gauge spokes anyway.

Yup... this is good! To re-spoke a wheel is on my must do list. To spoke in a sprocket mount would be a challenge. Would you need more length in the "J" (in the actual J section) end of the spoke to accomodate the thickness of the sprkt mount?

 

[Ludwig II]

I think you'd have to space the sprocket outwards anyway to avoid the chain hitting the tyre.

I see I misunderstood your question. If the new flange is the same thickness as the original hub flange, there is no difference, but the thread on each spoke might need a die running down t so it pulls into the rim properly.
