A super-durable disc brake touring, trekking and E-bike rim for the 21st century; the U 663 utility rim is a great value option for a huge range of bikes
System weight limit of 180 KG means that even heavily laden cargo bikes will be fine on the U 663
30 mm inner width to give good support to wider tyres when under load
The U 663 features a thicker, reinforced spoke bed, increasing Pull-through force by 20% at a key failure point for E-bikes and greatly extending fatigue life for minimal weight gain
The tubeless ready optimized rim bed provides fast tyre installation, a great tyre fit, and quick trouble-free tubeless setup but can be run just fine with traditional clinchers if you prefer
Outer width 35 mm Inner width 30 mm
Height 22 mm
