I'm a tradie, and keep my most-used tools in my tankbag, which I carry with me onto job sites. But some tools are heavy/cumbersome and life would be easier if I could leave them with the bike, in a relatively secure way, so I'm not having to lug them around everywhere. So today I took delivery of a lockable top-box. I really hate the look of them, they make even beautiful bikes seriously ugly, but convenience won the day. BUT ... the bolts that hold on the mounting plate can be accessed from the underside, and they have Allen-key heads. So I'm wondering ... do thieves carry Allen keys?
