A SeaSucker on-line exclusive! Tired of throwing your front wheels in the trunk? Pissed about cleaning your tire’s mud off the back seat on the way home from an epic ride? Mount the Side Loader onto your roof, trunk, door, or wherever. Made for standard road, cross and MTB wheels, but requires the MTB Plugs (available HERE) to hold a 15mm through-axle. Made from one of our Add-On Wheel Holders, it mounts with two 6" SeaSucker vacuum cups. NOTE: 20mm through-axle wheels are not invited to this party.
