Upon purchasing my bike that came with this rear wheel lock, I figured it was mostly useless. However, I'm wondering if it could be trusted to secure the rear wheel? My cable isn't long enough to go through both tires and the frame and also around a bike rack. It's either the front tire and frame to the rack, or both tires and frame without the rack. If I lock my bike up by sending the cable through the front tire and frame and bike rack, with the rear wheel lock on can I expect my rear wheel to still be there when I come back?
