Together with the Hexlox Key - and your personal and secret Hexlox Key Code - the Hexlox protects your cranks, (and perhaps your GPS tracker if fitted) from the tea leaves

The Hexlox 8mm is a small, stainless steel insert that protects virtually any part of your bike - instantly.

Simply Insert your Hexlox into any steel hex bolt you want to protect - this effectively blocks access to your bolt for a potential thief equipped with a hex tool/Allen key.
