Whyte Security Tool A feature of many Whyte city bikes is that their front wheels are bolted in place with a security skewer rather than a QR (quick release) to help prevent wheel theft. To remove or fit the front wheel, you need the Whyte Security Tool. At first sight, the Security Tool looks like an Allen hex key. However, the Whyte Security Tool is pentagonal so it will baffle any passing multi-tool-toting wheel thief . The Whyte Security Tool comes with a wee key ring to make it more portable. The Whyte Security Tool weighs 10g.
