Any question answered...

Does such a thing as a security chain tug exist or did I just invent a potential new theft deterrent?

am thinking of a chaintug that tightens with a unique tool (torx might even do) and prevents the rear wheel from being removed without having the tool to undo the tug to give enough slack on the chain or to break the chain itself.

not as secure as pitlocks granted but would make it bit harder to steal the rear wheel if you were locking front wheel/frame only.

Has someone been nicking wheels again in St johns sq?
