Can someone confirm my suspicion that the Kaisai hubs Riv is selling are just rebadged SP's?
If they are, SP/Kaisai are significantly lighter and more efficient than Shimano DN-3N7x or 3N80 dynamos. They are pretty close to Schimdt SON hubs in terms of weight and efficiency but are about half the price. SON hubs have some advantages: 1. SON produces a wide body version that makes wheel build stronger because they ate less dished. 2. SON has a version. That allows you to have wires built into your fork legs and therefore looks like there is no wire sticking out from the hub 3. SON hubs can rotate in either directions so the electrode can be either on the drive or line-drive side to allow flexibility I options in where you want to mount your lamp. 4. SON hubs have this nifty pressurized hub chamber to prevent moisture from building up. That being said, these benefits are marginal for my use cases so all but one of my and my wife's dynamo set ups (and we have 7 bikes between the two of us that have dynamos) use SP hubs.
