The Princess front hub uses straight pull spokes and only one external flange to save weight. The non-driveside body is drilled and the axle needs to be removed to insert the spokes. A bonded carbon band is used to reinforce the hub shell to stop the spokes pulling through at the absolute minimum weight.<br />
Tune are based in the Black Forest and focus on extremely high-end parts with every detail to the extreme. The front Princess and rear Prince hubs weigh a mere 84g and 180g respectivly. They are priced at a whopping €400 and €700, and there is a CeramicSpeed bearing upgrade option for another €500.<br />
