DT Swiss EX 471 Rim - Black - 32 Hole - 29 Inch eBay decreased weight and added durabilityMade famous by Aaron Gwin's tyreless DH run, the EX 471 is a bombproof rim that will hold up to every type of riding. The EX 471 is the ultimate rim for Enduro racing and has even been used on the World Cup DH circuit. The EX 471 is the perfect combination of weight and durability. These rims will hold up to the most aggressive riding and as Gwin demonstrated, they are capable of holding up to a DH run without a tyre (probably best to not try this).
