Why can't I find a drive hub with a larger flange on the left side than on the right, so I can tighten all the spokes to the same tension?

Is it the racing industry that has decided that it just is not worth making the wheel stronger laterally? I had problems finding cones for the shimano slx 675 hub I have two of , so now I must find a new cartridge bearing hub for my heavy cycle truck.

Velocity had an MTB hub built that way, but it seems to have disappeared off their buy-able list.

  • I think you have that backwards, the spokes are tighter on the right side so you want a larger flange there, surely? But really, if you want even spoke tension get an IGH. – Móż Aug 30 '16 at 22:50

You mean larger right side flange. Making the left side larger on a derailer wheel would exacerbate the tension disparity, not equalize it.

There are companies that do it. The reason it's not more common is that the difference has to be pretty radical (i.e. a way more expensive shell to produce) before the tension disparity is affected much, and at the same time, it doesn't take much difference at all before lacing the hub gets difficult using conventional j-bend spokes.

On 6-bolt hubs, the left side already has to be around 58mm, so making the right side much larger means starting with just a really big piece of al, and I believe that's why it's seldom done.

The only tall left side mountain hub I know of is the DMR Revolver. I have no idea why they did it that way. But if you want equal spoke tensions, don't buy that hub.

  • thanks, recon that is why the criss king hub is so expensive... – Nohj Yesdnil Sep 1 '16 at 17:23
