DT Swiss is a brand of legend among bicycle wheel components. First quality products from this Swiss manufacturer have been the brand's benchmark since its inception. Nothing matters to DT except the durability and performance of the parts it produces. For years, the 240s hubs, ceramic 180s, XM, EX, XR series rims, which have been appreciated by literally every mountain and road cycling enthusiast, are in a class of their own. A completely separate, unsurpassed category is also formed by spokes with Champion, Competition, Revolution or top Aerolite models.

A lightweight rim width for DH was unimaginable just a few years ago. Top-class materials and intensive research have made it possible. DT Swiss technologists today know exactly how a lightweight rim can be produced to perform its functions perfectly. That's why the XM 421 rim is as light as possible for an MTB rim, while having enough strength to not be afraid of the challenges of Trail riding.
