The Trek Dreadlocks Resettable Combination Cable Lock uses a four digit combination, like many other locks, but it also lets you reset your combo to keep ‘em guessing. The lock itself is lightweight, and it’s also self-coiling for easy storage. It has a durable vinyl cover to protect your precious bike’s paint job while you lock up. The Trek Dreadlocks Resettable Combination Cable Lock also features a lifetime limited warranty and comes with a handy frame mount. You can purchase it at the Trek online shop for $19.99 – $24.99.
