Rear Wheel

[H2Eric]

I have a K3 frame and swinging arm, I also have a rear wheel which came out of a K7, which of course will not fit as the later swinging arms were wider at the rear. It's not just the spacers that are different as the K7 wheel will not center in the K3 swinging arm. Is it perchance that it's the sprocket carrier that's the issue here?



Some measurements


back of sprocket to flange


Depth of bearing housing to sprocket



If the earlier sprocket carriers are narrower and assuming that the cush drive is the same then providing I can find one perhaps I might be able to use the K7 hub with the K3

Any info gratefully received
Thanks

I've no info that can help, but may be taking your caliper out to a bike meet would get you something to mesure if you can't get info here.

Hey H2Eric,

Yes, the sprocket carriers from the K2-K6 are narrower than the K7's. There is a 10 m/m difference, because the double bearing off the axle that carries the front sprocket is also 10 m/m wider.

Left is earlier type, right is K7.

Hi Rob
