Re:

What does this measure from the drive side cup to the end of the axle? Sorry to be a weight weenie but do you also have a weight?
 
Re: UN 71 bottom bracket

I measured the length of the axle width - this is ideal if you want to run older cranks (grafton etc)

Reported as weighing 273grams
 
Re: UN 71 bottom bracket

No this is 21.4mm from the edge of the drive side cup to the end of the axle.

However I do have a UN51 BB with the following if of use with 27.8mm
