Walker Brothers Ethereal disc wheels are like no other. Each wheel is constructed with four separate thin and lightweight carbon skins, meticulously hand laid to a precise pattern to maximise strength to weight ratio. The Ethereal SSD has been specifically designed for optimum performance in Sprint track events where stiffness and power transferal are paramount. It has fantastic lateral stiffness due to it’s wide flange to flang width and also its massive 130mm inner carbon flange diameter. This both increases the angle and shortens the length of the rim to hub connection. With weight being less important, the Ethereal SSD has literally double the carbon fibre than it’s ESD brother. This is the first disc wheel specifically designed for sprint and power events.
As of immediate effect, we are fitting all our Ethereal Track Discs with Kogel Ceramic bearings. The Silicon Nitride used to make ceramic bearings combines a set of material properties that make it perfect for bicycle bearings. The material is hard, resistant to wear, can be made into perfectly round balls with super tight tolerances and can be polished smoother than any metal. On top of all that, ceramic bearings do not rust or oxidise.
Rim: Carbon 23mm rim
Skins: Full carbon hand laid side skins
Hub: Walker Brothers alloy Al7075 sealed bearing system. Oversized drive side flange for increased stiffness.
