The SP PD-8X is more efficient, technologically advanced and simpler than competing hub dynamos while also being 40 grams lighter in weight than any QR15 hub dynamo available.
Current tests show the PD-8X to have achieved a new record breaking efficiency of 78 percent (i.e. watts of mechanical energy converted directly in watts of electrical energy - minus wasted muscular effort that would otherwise be propelling rider and bicycle forward), ranking it above the SP 8 series hub dynamos which previously ranked highest in the world at 72 percent.
The PD-8X is the 6 bolt disc model. For centrelock discs, see the PL-8X.
