As used by UCI World Cup Gold medalists, team KGF. Walker Brothers Ethereal disc wheels are like no other. Each wheel is constructed using four separate super thin and lightweight carbon skins, meticulously hand laid to a precise pattern to maximise strength to weight ratio. The Ethereal ESD has been specifically designed for optimum performance in endurance track events like pursuit races, where aerodynamics, acceleration from start, and smoothness of ride are paramount. We believe the Ethereal ESD has the lightest rim weight of any disc wheel on the market for incredible acceleration.
Tested numerous times by 3 x National track champion Dan Bigham’s Watt shop, the Ethereal ESD has consistently and significantly outperformed top brands such as Mavic Comete, Lightweight Autobahn, Corima and Pro lite.
As of immediate effect, we are fitting all our Ethereal Track Disc 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 oxidize.
