Scott, this was an *outstanding* report! I have bookmarked it in case I decide to service my SP hubs when the time comes. About 8 years ago, before I got my first SP hub, I had a bearing failure in a Dahon "Joule" ("Joule 1"... subsequent Joule hubs for Dahon and, eventually, Tern, are made by SP!) dynohub at about the 2,000 mile mark. I was told the hub was not serviceable... not what I wanted to hear! Eventually, I figured out how to replace the bearings, which is just about the only part of a dynohub that can (or should) wear out. I documented the repair
HERE. It appears that the service of the SP hub requires a bit more technical expertise than the Joule 1, so I'm glad to have your experience to temper my enthusiasm to service them myself! There's an SP service center in California, apparently (see above).
Best,
Steve
