My first question here so sorry if this has been beaten to death. I have read the few threads here on this topic. I have a new Cinelli Super Corsa with 130mm spacing and want to build with vintage mid 1980's SR components. I purchsed a vintage set of NR/SR hubs that were advertized as 125mm spacing, 32 hole, 35x24F. I was planning to add 4 mm of spacer on the left side, recenter everything, and then see if enough threads make it into the dropouts. If not I would buy a 10x141mm axle and build that up.
Ok. I took the rear hub apart to clean it and found that the axle was 134mm. Shouldn't a QR axle for 126mm spacing be 137mm? Is this the wrong size axle for this hub? Or did Campagnolo make NR/SR hub that was thinner (hub measurement without the axle) for a smaller spacing of 123mm?
