HEXLOX - THE WORLD’S SMARTEST (AND BEST-LOOKING) ANTI-THEFT SYSTEM FOR BIKE PARTS.

Hexlox can protect virtually any bicycle part like wheels, saddle, seat post, and more, from theft with an elegant and almost weightless solution. Hexlox is designed and manufactured in security conscious Germany - for riders all over the world. 

You will need to know which size security bolt you need. This is simple. Whatever size allen key you would use to undo the bolt is the size of hexlox you need. 

You will then need to get Key option A or B, whichever matches the Hexlox option, from here.

For example if you are looking to get a Hexlox bolt for your seat clamp, and it takes a 5mm allen key, then you need to get the 5mm option. You then need to choose the key option A or B.
