I get to build the most expensive *front* wheel I have ever built today. It is a disk brake compatible generator front hub from Schmidt (a German company that you can check out at Peter White Cycles) laced up to a Mavic X717 Disc Rim, black double butted DT spokes. Ironically, this is the matching wheel to the most expensive rear wheel I have built: Rohloff to X717. Total value of wheel set is approaching $2k. These wheels are completely off-road touring specific, and so far the customer loves them.
The lights that are to be used with the Schmidt hub are obscenely bright. One of my favorite stories about these lights is a customer/friend of mine who set up this system on a Heron for long rides. He set off for a night ride and went to Washington Park for a nice long spin. Everywhere we rode around, people acted like they were caught by the cops. They thought he was on a silect motorcycle. This guy is a retired officer, so he laughs everytime it gets brought up. Great stuff.
