    SP PD-8X Dynamo Hub - Good Rotations

    Shutter Precision

    SP PD-8X Dynamo Hub

    $389.99

    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.

    • QR15 compatible
    • Comes complete with adaptors for standard 9mm QRs
    • Weight: 420g
    • Quick release not included

    The PD-8X is the 6 bolt disc model. For centerlock discs, see the PL-8X.

    We also offer dynamo wheel builds on any dynamo hub - contact us for availability and advice on build options.

    Note: Please allow up to 2 weeks for delivery.
