SS/Fixed Hubs available in the UK

Shimano hubs are all forged

While Shimano (as other Japanese premiere vendors) are big on cold forging their high end hubs tend to NOT be cold forged but spun. Our favorite NJS Dura Ace 7600 and 7710 track hubs are good examples. With a probable few exceptions--- such as the Campagnolo C-Record--- most all NJS certified hubs, I think, were spun.

Other methods of forming round metal parts include hydroforming, stamping, forging and casting. These other methods generally have a higher fixed cost, but a lower variable cost than metal spinning. As machinery for commercial applications has improved, parts are being spun with thicker materials in excess of 25mm thick steel. Conventional spinning also wastes a considerably smaller amount of material than other methods.
Objects can be built using one piece of material to produce parts without seams. Without seams, a part can withstand higher internal or external pressure exerted on it. For example: scuba tanks and CO2 cartridges.
One disadvantage of metal spinning is that if a crack forms or the object is dented, it must be scrapped. Repairing the object is not cost-effective.

Spinning results in stronger more failure resistant hubs.
