I am off on tour on Wednesday and I have just fitted my bombproof touring wheels (heavy, thick rimmed, 700*32, 36 spoke jobbies with Schwalbe Marathon+ tyres) in preparation and, as always, it now feels like I am trying to peddle push a tank! I just wondered, as the tour will be on good roads in France and Northern Spain without masses of kit (still undecided about the tent), could I stick with my much lighter and smoother rolling Audax wheels? It wouldn't normally bother me, but the tour is due to end when I meet my family in Valence, so the prospect of an unburdened ascent of Ventoux is on the cards. The lighter wheels have held up well on Audax rides, but I don't know how they perform under a heavier load and I don't want to spend half the trip replacing spokes. Any opinions?
