At $525, the Crust Rim Brake Wheels are an ideal option for your 650b QR bike. They were designed with 42-48 mm tires in mind, are double walled for durability, but slimmed down where they can be to keep them as light as possible. For rear spacing, there are two options: 130 mm and 135mm. The driver in each rear hub has 3 pawls with 3 teeth each that provide a nice, crisp engagement. You can also choose between a dynamo with Shutter Precision for $100 more or non-dynamo front wheel.
