Square taper bb size and chainset

[Crankarm]

I don't know what the chaiset make is, I haven't seen any markings identifying the manufacturer. It is a double, with riveted chainrings, steel as far as I can tell, 48T and I think 42T, though I haven't actually checked the size of the small one.

Posting a picture or two would be very helpful to you.

I found a 70x134 spindle in sjs, no good for me though, I need 68.

Put a 1mm shim washer under each side of the bracket tube. Campagnolo used to do a 130-something spindle in their MTB range, I know cos I've got one somewhere ...

You will feel the wear ridge on the cups if they are worn.

Found one! I thought I had checked Amazon thoroughly, and looking again today this turns up:

https://www.amazon.co.uk/NECO-COMPL...,+110mm+to+127.5mm+(110mm+AXLE+68mm+BB+SHELL)

The title description says up to 127.5, but the drop down list has 134.5 as available, I reckon that is close enough for what I need, as there is enough clearance between the chainset and the frame, that 1.5mm should not be a problem.
