I've been following various debates about wider rims, and would now like to give them a try. Mr current set-up is 28 spoke Ambrosio Excellights on Ambrosio hubs. I weigh 85 kgs, and have always been light on decent wheels. Does anyone have experience of the A23 rims, and if so can they suggest a decent, lightish, strongish build? I should add that the rear hub needs to be Campagnolo 10 compatible.
