Tune Prince and Princess Hubs

 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.
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.
