Super Wide Disc Braking Wheels for Road, Gravel, Adventure & CX - unbeatable value & performance, and every one precision hand built in the UK

Fat Boy Koppenstoppers. Like the Koppenbergs, only with extra Stoppenberg.

These wheels are made with my fast Koppenberg DM8 Fat Boy Rims, and precision hand built onto lightweight SPN centre-lock disc hubs for even faster stopping. Available to fit bikes with standard dropouts for QR axles, or for the latest generation 12 and 15mm thru-axles. Let us know your axle requirements when you checkout, via the Comments Box.

If you're choosing a disc build, please choose disc as your hub type from the options menu, and tell us your front and rear axle requirements in the Comments Box found at the checkout page.  Weights for all wheels except the Gravel Kings are quoted below built on standard road hubs. Disc hubs add just under 90g / pair.


Available in all-new colours: Havana Smoke, Cobalt Azure, and hand polished Raw Alloy

Currently riding rim brakes but thinking your next bike might have discs? Or maybe you already have both bikes in your stable?

No problem - these Fat Boys are disc & rim brake compatible!  Just choose the axle types you need, or add a second set of axles for your other bike from our spares store.
