The SP SV9 is one of the smallest Dynamo hubs on the market.
Developed for road use, this dyno hub packs some power for its small size. A unique but efficient aerodynamic shape means its only a little larger than a golf ball at the centre of the hub.
Producing 6V 3W* at normal riding speeds, its more than enough to power your dynamo light set or charger. Tried and tested this hub not only offers a low rolling resistance but is lightweight to boot!
Never get caught out without lights again, as the days draw shorter and the roads stretches longer the SV9 will keep you riding into the night.
Available in variety of hole drillings, even the weight weenies cannot argue with this hub.
*Note: SV9 hubs are now labelled as 6V 1.5w. This is to comply with the strict German StVZO regulations.
When used with 26” or 700c wheels the output can drop very slightly below 6V3 W at low speeds, but is 6V 3W at normal riding speeds
For 20” or smaller wheels the output is 6V 3W
The hub is suitable for all lights or accessories designed for 6V 3W hubs
Please note: In the hand, all dynamo hubs will have resistance when rotated. This is perfectly normal, and a function of the magnets inside operating. This feeling will not be discernable when the bike is ridden at speed.
