These 29 inch 700c e-bike/trekking/touring/mountain bike rear wheels incorporate black 32 hole DT Swiss U623 hybrid disc rims, black Shimano QB400, 6-bolt disc rear hubs, Halo black spokes and nipples. The new DT Swiss U623 hybrid rim is a super-durable disc brake touring, trekking and E-bike rim for the 21st century, giving a great value option for a huge range of bikes. With an inner rim width of 25mm, and outer rim width of 30mm, the U623 is ideal for tyres ranging between 33-60c. The tubeless ready optimised rim bed provides fast tyre installation, a great tyre fit, and quick trouble-free tubeless setup. However, it can be run just fine with traditional clinchers if you prefer. The rim is drilled for Schrader valves but includes an adapter for Presta valves. The U623 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. It has a fantastic system weight limit of 180 kg, which means that even heavily laden cargo bikes will be fine on the U623. The Shimano QB400 6-bolt disc brake mount hubs are part of the new Shimano CUES system. They have high quality seals, and offer well-known durability, reliability and performance. The hubs are set for 135mm quick release (skewer provided), with a Shimano HG freehub that will take 8 to 12 speed MTB cassettes, or up to 10 speed road cassettes. The rims are 3-cross laced to the hubs with Halo black spokes and nipples. Price includes insured and tracked Parcelforce postage.
