Campagnolo Record Pista crankset

One of the few track parts I still owned a year ago. All other track stuff (and loads of other Shimano, Campagnolo, Cinelli... etc ... items) I have given or just thrown away. Such a shame.
This set with crank length of 170mm and bolt circle diameter (BCD) of 144mm still works well and is compatible with lots of old and new stuff.
At the moment I only have a Super Record chain ring 53T for a 3/32" chain. This ring is perfect, but it's always good to have an additional ring with 50 or 52T, either 3/32" or 1/8". Campagnolo of course.
If there's a good occasion, I will buy a similar set with 165mm cranks. For steeper tracks and for the kids when they grow up.
