I have a set of Shimano 6700wheels that I no longer use. The are 8/9/10 sp compatible and weight 1,652 grams.
I orginially bought them for racing but am now running the wider Velocity A23 rims on both my sets of training and racing wheels. The wheels have had minimal use with no rim wear and perfectly true. They have a low spoke count (16F/20R) and I'd recommend them for a sub 75kg rider.
I'll sell the wheelset for $150 which is a lot cheaper than Wiggle! Please PM if you're interested in grabing them.
Front wheel $170.62
