I have about 1000 km on a new SP PV-8. This is the only hub alternator I have used so I can't compare to others.
Bought it on ebay in USA, got a good price, received it quickly from Taiwan. SJS told me that they only had 32H, I wanted 36H.
At walking speed, I get just barely enough flickering light on one (discontinued) B&M Oval Lumotec LED headlamp to see where I am going, no taillight. Currently have two of the Oval Lumotec headlamps wired in series, need about 4.5 mph to get any flickering light, but am very happy with how much light I get with the pair at higher speeds. The pair of lights I have do not have a switch, I plug the wire connector into the hub to use the lights, unplug when I want to turn them off.
I read somewhere that the connector is the same as the Shimano connector but I can't confirm this. Obtaining a Shimano connector is likely easier than obtaining the connector from SP. I zip-tied wires and connector to the fork leg, so if the Shimano connector also works, that will be handy if I use that wheel on a different bike. Then I can zip-tie wires and a connector to the other bike fork leg so each bike is ready for using that wheel. (Unfortunately, may need to swap brake pads, have the CSS rim on the wheel with the SP hub.)
Am happy with the purchase.
Thanks for the link on the catalog. This hub is the only critical part of my Nomad build that does not have a history of touring durability and reliability so I was happy to read the piece on somebody using it for self-supported mountain bike racing. Until I read this I was a bit nervous about using an untested hub on a long rough tour, but feel better about my choice now.
