I¹ve but my obscure part obsession on hold to conquer an Italian build.
Looking for a set of Campagnolo Pista Cranks 165mm, preferably with chainring/chainring bolts and dust caps, but the latter two are optional. My understanding is the NR/SR arms are the same except for the chainrings. So I guess it makes it a moot point unless you have the ring. In that case, my preference would be SR.
Please contact me off list.
