So... as I'm working towards a Brevet series this year, I've just ordered a Schmidt dyno hub to be built into a Mavic Open Pro wheel (32 hole black rim, black spokes and nipples) - (rear wheel to match, with Ultegra hub, 9 spd cassette). I'll still rely on batteries for a small Cateye light on the bars, which will double for map reading / repair light / etc. - but my primary forward lights will be dyno powered. Rear to be battery LED, as they seem to last forever.
I'm still deciding on which lights, and how many (1 or 2) to run. After getting it sorted out and installed, I'll post a full review.
I've been frustrated with my NiteRider system. Been sent back to the factory twice. Good customer service, but I've had unpredictable charge times and shortcomings with the batteries and wiring. Also increasingly short burn times. (it recently quit on an 18 mile country road commute, about halfway through the ride) The longest run time I've ever had was just under 2 hours. I've also used Cateye battery lights for primary lighting, but do not want to rely on this for a 24 hour event, or a multi-day event that requires lots of night riding.
My LBS, the West Hill Shop is building the wheels, with the hub coming from Peter White.
I'll be designing a bracket with a machinist friend so I can move the lights quickly between my LeMond, Trek 520, and the Bridgestone (should I ever spend the time and finish the rebuild...)
