I should point out that @
JohnDThompson has a Viscount set up almost exactly the same as my Lambert. It might be fun to hear his thoughts on it as well.
Yes, I do:
I use it as my bad-weather bike, and rode a century in the rain on it a couple years ago. In general, I'm satisfied with the hub. My biggest complaint is the gear ratios are odd: 0.625/0.75/1.0 -- I'd prefer those of the old ASC hub: 0.75/0.90/1.0, which would give me a couple closely spaced gears for most of my riding, and a bail-out gear for climbing. With the S3X, I set it up so the 0.75 middle gear gets most of my riding, the 0.625 gives a little help on hills, and the 1.0 is seldom used except with tailwinds and downhills.
