I had to exchange at least one per day starting near Agrigento. This is outrageous given that we had a complete new wheel mounted by Koen on December 8th. He enquired and the result was that similar problems with early corrosion occured with the black (Sapim) spokes to others before, and advised to exchange all of them. The Rohloff representative in Italy (Werner from Rewelbikes in Bolzano/Bozen) had a set in his workshop and kindly offered to send them to a hotel address in Reggio di Calabria.
