I'm wondering whether anyone has seen drag stats for the Sturmey Archer X-FDD?? The only good numbers I've managed to find online (in this VBQ article) don't include the X-FDD and show *much* greater drag with the lights off for the older (HB-NX*) vs newer (DH-3N*) Shimano models. In fact, on the older Shimanos, the drag barely changes regardless of whether this light is switched on or off (!). I read a post on another forum suggesting the lights-off drag of the X-FDD might be comparable to the older Shimano models, but no solid data to support this comparison. Supposedly, Shimano and SA hubs use the same Sanyo internals, but I can't tell which Shimano internals (the not-so-great Nexus or the newer DH-3N*) are supposedly comparable.
Anybody happen to know for sure about the drag and/or the internals? I really like the features on the SA hub, but if it really does drag quite a bit at high speeds when disengaged, that might be a deal-breaker.
