These are the Koppenstoppers.
Just like Koppenberg - but with extra Stoppenberg.
These wheels are made with my fast Koppenberg DM8 Fat Boy Rims, and precision hand built onto these 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.
If you're choosing a disc version of the 838, 845 or 858, don't forget to choose disc hubs from the options list. The weights quoted for these wheels below are for standard road hub builds.
Disc hubs weigh a bit more, adding just under 90g / pair.
