The CR18 is a great rim, but in this case I'd go with something wider and more sturdy. A Sun Rhyno Lite would be similar in price, and better suited for the task. If the bike is being setup Tubeless, the Rhyno Lite isn't specifically designed for it, though I've heard plenty of people have had success getting it to work anyways. If you want a tubeless specific rim, DT Swiss 533D is currently available for bike shops to order at half their normal cost.
