Help sourcing tube clamps

Afternoon All,

I am trying to locate a source for tube clamps with an inside diameter of 52mm but am having no luck, perhaps they go by another name I am not aware of?

I am looking to go for a similar idea as Futr have done with the Beta as seen here on their concentric bottom bracket:



Any and all ideas welcome?

split shaft collars, locking shaft collars, but good luck finding them in 52mm. You could also try some 52mm ID tubing, or 2" ID tubing and open it up a bit, cut it down the length with a grinder cutoff wheel, then weld two nuts on with one drilled out.

Thanks for the reply.

I've found some roll bar spot light mounts in 52mm and fork tube clamps for indicators but no idea if they'll be strong enough.

I'll probably end up just making some at this rate!
