The Zefal K-Traz Double Loop Security Cable 220cm is a simple way to add extra protection to your bike when using a D-lock or padlock. This bike lock cable gives you the reach to secure wheels, frames and accessories that a standard lock can’t cover. It’s a practical upgrade for anyone wanting more complete bike security.

With a generous 220cm length, it’s ideal when you’re locking up in awkward spots or need to loop through both wheels and the frame. The double loop design makes it easy to pair with your existing lock, giving you more flexibility without carrying a second heavy lock.

Who is this double loop security cable for?

Ideal for riders who already use a D-lock or padlock and want to secure more of their bike, like both wheels or the saddle. Great for commuters, students and anyone locking up in public areas where quick-release parts are at risk.

Who is this not for?

This isn’t a standalone bike lock. If you need primary theft protection, you’ll still need a proper D-lock or similar. It’s also not suited for high-risk areas where heavy-duty locking is essential on its own.

Why we love it

We’ve found this is one of the easiest ways to upgrade your existing lock setup without overcomplicating things. The extra length makes a real difference, especially when racks or posts aren’t in the ideal position.

Hot tip!

Run the cable through both wheels and the saddle rails, then secure it with your D-lock through the frame. It’s a quick way to protect the parts most commonly targeted for theft.
