I'm going to install a SR crank with a single 48t ring on it, onto a Campy Veloce BB. I'm wondering why the fixed require more space in the spindle than a double or triple? Also, wanting to make sure the SR cranks will fit on my Veloce- I read somewhere just now they may not. Any help appreciated.
Below is the note from the seller of crank and BB: 111mm minimum, common Campy BB come with 102mm for road or 111mm for all Campy track/pista crankset.
We rarely see 107mm bottom bracket, not sure this must be a recommended by Campagnolo 107mm+ for clearance.
The Record carbon shell w/aluminum cups is lighter but the price is 3 times more than the steel shell w/aluminum cups, but both are seal bearing. The weight of carbon BB is 6.6oz and steel BB is 11oz, in business we would like to offer you the lighter weight and higher price item. But honestly, we have used steel on our bikes but hard to tell the different...so please let us know which one you like.
