The WR40 was built with one goal in mind: making the best rim possible for long distance gravel racing or riding. With a massive 25mm inner diameter, the WR40 provides a stable profile for even the widest gravel tires. Thanks to its mid-depth profile, the WR38 is deep enough to provide aerodynamic help when riding alone across gravel plains, but not so deep that is hard to control in crosswinds. Whether you find yourself racing across the Midwest or month long backpacking trip, the WR38 might just be the perfect match.
