FWIW I built a 48 spoke rear wheel , Phil wood Freewheel hub.. A 700c rim
no soldering job , It s not a banked track velodrome ..
broke 1 spoke .. you have to undo the soldering to replace 1 spoke
the use of a freewheel hub was part of the extra spoke thing ..
only carried the spare spokes and the freewheel tool..
borrowed the Big F wrench when I needed it. week after the 1 spoke broke
I built the wheels .. spot truing brought it back in true with 47 spokes ..
