Subject: [CR]Campy NR Cranks

Hey experts, I have several sets of undated Campy NR cranksets. These particular ones are 144BCD. I have some questions. Does anyone know when the pedal thread size info was moved from above the pedal hole to below the peddle hole. Secondly, the cranks which appear to be earlier have a slightly smaller "boss" around the pedal hole. My recollection is that the earlier ones were about 31mm across and the later ones 33mm across. The later dated cranks all appear to have the wider boss. Does anyone know when the wider boss was adapted? Happy pedaling. Tom Hansen
