U 533 This robust 22 mm wide rim is designed to withstand long-distance touring. Built to last, it suits the demands of e-touring and trekking bikes, which are now used over long distances and often on rough tracks. Thanks to its high-strength 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.
