6" SeaSucker with a 1.5" wide hook-and-loop strap to secure your bike’s rear wheel and keep it from moving left or right when driving. This item comes standard with the Talon, Mini Bomber and Bomber bike racks – it does not need to be ordered separately. Sometimes the standard 6? Rear Wheel Strap that’s provided with the Talon, Mini Bomber or Bomber doesn’t fit in the space available on your car, so we offer a more compact version with our smaller 4.5" SeaSucker vacuum pad. The Compact Rear Wheel Strap does NOT have the cupped rear wheel housing that comes standard with the regular Rear Wheel Strap.
