FWIW, overall theft is still an issue, but more and more people are stealing components off locked bikes.

An inexpensive "security bit" fastener kit would be nice. But the bit would have to be proprietary. Something like $35 for the kit. Include replacements for the QR skewers that are "security bit" also.

Most roadies with expensive bikes won't lock it up for a day on end outdoors. It's the quick cafe' stop that necessitates something that would deter a daylight hours criminal in plain sight enough to not do it. The newer "band" locks are a good idea, but people are complaining that they're tripped with just a pocket knife and often jam upon opening.

Locking skewer and component hardware kit would mean a commuter leaving a bike for a long time would just need to secure ONE lock to the frameset instead of the usual two: frameset AND wheels.
