Those SKS fenders are sweet. Possibly the little mud flap piece might cause interference with your 13s also. It is clearly structural. One thing I like about those SKS, is that they are clearly lower profile than most, and virtually aero. I have been planing something similar (though conventionally attached) since I built my Bamboo fenders in 05. Those clearly showed me that I did not need the standard wide profile most fenders have.

The berthoud parts look like a good solution, but you still need to fab an attachment point for your wires at the fenders.
