The SeaSucker Compact Rear Wheel Strap is a more compact version of the standard Rear Wheel Strap, featuring a smaller 11 cm SeaSucker vacuum pad. This is ideal if the standard 15 cm Rear Wheel Strap cup does not fit the available space on your car. Please note that the Compact Rear Wheel Strap does NOT have the cupped rear wheel housing found on the regular Rear Wheel Strap. The 11cm vacuum mounts have a rated pull strength of 60 kg when pulling straight out from the center, though pull strength on a shear load (pulling from the side) will be less. Vacuum mounts are designed to last and will warn you when they need repumping by extending a plunger with an orange indicator band. For optimal performance, ensure the mounting surface and the SeaSucker vacuum pad are clean. A quick wipe with a damp paper towel is recommended before attaching. The strap is 56cm long and fits even fat bike wheels.
