• I'm having the same problem. My problem is that the broadest readily available BB in Campag is 115mm. Campag did manufacture a 120mm in the eighties but I haven't sourced one yet.115mm is not enough for the lugs thar house the chain ring bolts to clear the stays on the frame. Shimano provide the width but everyoune advises against, as the square taper is slightly different and the cranks would be in danger of coming loose. The alternatives are: 1) grind off the lugs on the Strada so that they clear the frame. 2) Sell the Strada and buy a genuine track spider from any manufacturer you like, inc. Campag, realising that the bracket will be acquired to match your choice.
