Default Is there an updated Dynotest somewhere?

My SP PV8 hub dynamo has been in service for a few years now.? I guess
that means it's done near 30,000km already, with no issues to report.

Characteristics very similar to a SON, but without the price tag,


SP claims that its tests show higher efficiency than the SON. I guess
that's as valid a conclusion as the tests published by SON.



SP is something of a puzzle. They used a laminated armature, but
it's still a clawpole design. I'd be curious to know their reasoning.
From where I sit it looks too wrongheaded to be worth spending much
money on, but if one came to hand it'd be worth exploring. It looks
as if the cost is somewhere over 100 US$

Does SP have a US dealer?


Thanks for posting!
