The Surly Clown Royal is a 100mm-wide fat bike rim designed exclusively for the 6.2" Molenda tire. Its 24-inch diameter maxes out tire volume for Moonlander's frame for ultimate flotation and traction. This rim is high in durability and low in maintenance thanks to a tubeless ready rim bed for easier tubeless tire setup with a no-stretch rim strip, plus tubeless rim tape. The ramped cross-section approaching the Bead Seat stabilizes the tire bead and casing for easy setup.
