Here's my gold set of L&M Downhill cranks.. (ATB pattern spider)
Had them since new, bought in 1998/99 for £125.00
A friend at the time had a set of the XC ones, only difference I could see was that his had a lot of CNC work on the back of the arms and obviously omitted the word 'Downhill' other than that they were the same.
I still have the original box which I could dig out and take a pic of if anyone is interested?
