Thanks to everyone for their suggestions about how to rejuvinate old saddles.
The archives, on the whole, recommend against 4x wheels. The general feeling is that they have no advantage over 3x wheels. If that is so, why did so many 50' and 60's British bikes use 4x patterns on their 32/40 wheelsets?
I'd like to build an Airlite Large Flange Hub - Fiamme Red Label rim wheelset. Should I expect any problems when I lace old hubs with old rims like these using a 4x pattern?
