A broad, reinforced rim for a bike that carries more than its rider. The U 663 combines a 30mm internal width with a utility-focused alloy construction, giving wider tyres a supportive foundation for loaded urban, trekking and e-bike use.
The thicker spoke bed is designed for sustained loads. Several wheel diameters and drillings are available here, so match the exact bead-seat diameter, spoke count and Schrader valve requirement to the bike. A rim load rating alone never raises the limit of the rest of the bicycle.
Details
30mm internal width; 22mm rim depth
Disc brake only
Schrader valve drilling
Supplied as a rim, not a complete wheel. Spokes and hub are chosen separately for the build.
The 30mm internal profile gives an appropriate wide tyre a broad base. It is intended for the demands of utility riding, where bike, rider and luggage can put very different loads through a wheel than a lightweight road build.
Built For Repeated Use
A reinforced spoke bed helps the rim cope with the repeated loads of an everyday workhorse. Choose the wheel diameter and drilling for the actual bike rather than treating all U 663 variants as interchangeable.
