Joe said: Lightest wheelset I've ever seen (can flip bike if not properly anchored, see Bayliss post), not many were made and few have survived.
I own serial #6 and one time on a training ride, I tried to jump after a little break attempt that I didn't want to get away on me. When pulling on the bars, I ended up lifting the bike into this incredible wheelie-- the best I've ever done, even better than MTBing stuff I've done over the years in Crested Butte. After a long time airborne in front, I was able to come to grips with it, gently settling down into a grassy area beside the pavement. Yep, they are extremely light in the front end!
