Rivian R1S owners, need to haul some extra gear? These Wonderdriver cross bars are made specifically for your SUV (2022-2025 model years, and note – they are NOT for the R1T truck). They're a solid, heavy-duty option built to last. The crossbars are made from thick 2mm aircraft-grade aluminum with a tough black matte powder coat that resists corrosion. The mounting feet are also aluminum – a big upgrade over the plastic feet on some cheaper racks – which means better security and durability. They have a lockable core system to help keep your cargo (and the bars themselves) secure. The rated dynamic load capacity is 260 pounds (that's 118kg) when you're driving, which is plenty for roof boxes, kayaks, ladders, or cargo carriers. They have a low-profile, aerodynamic shape to help cut down on wind whistle at highway speeds. Installation is designed to be straightforward with clear labels and an Allen wrench included. You get a pair of crossbars, all the mounting hardware, and they offer a 1-year warranty. If you're planning a road trip, need to carry sports equipment, or just want the option for extra storage, these are a great fit for your R1S.
