Product Description

The Kryptonite Kryptoflex lock cable is the perfect addition to a U-lock, disc lock or padlock. If you want to protect your wheels from getting stolen, then the 4ft or 7ft Kryptoflex is ideal - especially if you’re riding on quick release wheels.

Lightweight, portable and very durable this Kryptonite lock cable blends the 3 key ingredients of any bike security product. The 10mm diameter braided steel cable has a greater core density than twisted cable for improved cutting resistance. Vinyl coating is a helpful feature for stopping scratches on your frame paintwork.

  • 10 mm diameter braided steel cable
  • Double-looped cable for use with all Kryptonite U-locks, disc locks, and padlocks

"2nd Noose"
Great item to be used on my partners bike after the success with the one Ive had for years Recommended product

"Kryptonite cable"
Great cable for securing your wheels 7ft when leaving your bike somewhere in town for a few hours. Its pretty light so easy enough to carry around in a backpack. Obviously a determined thief will cut through this but it clearly adds an extra layer of protection. Ive only been using it for a couple of weeks but its excellent value for money. Dont forget youll need a proper lock ideally a Ulock to secure the cable though!

"Kryptonite Krypotoflex Good value cable lock"
Much better product than I thought. Bought the 7ft version to lock up two bikes when on the rack or when leaving them in the city for shorter amounts of time obviously bolt cutters would get through this but for short stops its great. 7ft goes through both wheels which is handy. Stong cable but lightweight. Would recommend.

Best price for solid product. Bought to secure car winter wheels

"Kryptoflex 7ft cable"
The 7ft cable is a good length and is long enough to secure the seat thread itself through the rear wheel over the top of the frame and around the handlebars. Please note that this is just a cable though so a proper lock is required to attach it to the bike otherwise its useless.

Overall Rating:4 - Rating: 4 / 5
Really light and flexible for various locking options. Only suitable for front wheel or seat though this wouldnt last too long at the hands of a thief!

"Excellent bit of kit"
The 7 version is definately the way to go! I used to own the shorter version and many a time would get caught out by its lack of length. This is a sturdy bit of kit and works well with the Kryponite ULock. Well recommended

"sound investment "
Bought the 7ft version to lock my burley to my bike when out and about. Lightweight and strong enough to stop any opportunistic thief but wouldnt stop the more determined but was aware of this before purchasing.

works well with D lock not too long but probably not that secure either.

"Handy Cable"
Very useful cable having quick release on the wheels and seat of the bike I leave at the station when commuting the 7ft cable can thread through all. Very good quality product. Would not withstand good bolt cutters but nothing much will but it is certainly a deterrent.

"The best cable extension for a DU lock"
Great extension to further secure your bike long with a DU lock. Buy this one if you want to secure the front wheel as well as the rear wheelframe. The midsize one is recommended for a standard size hybridroad bike. The smaller length cable will not stretch from the front wheel to the back of the bike 56cm frame so the midsized cable is the one to plumb for. Purchased this along with the New York fahgettaboudit.
