U 533 This robust 22 mm wide rim is built to withstand long-distance touring. Designed to last, it suits the demands of e-touring and trekking bikes, which are now ridden over long distances and often on rough tracks. Thanks to its highly durable aluminium construction and reinforced rim profile, the maximum system weight is 140 kg, so you can easily carry more load. Whether it's a Sunday outing or a multi-day tour: the choice is yours.
