Combination code wheel skewers and saddle clamp bolts from Australian brand Sphyke are now available in Europe for the first time.
With Sphyke’s C3N system, you replace your wheel's quick-release skewer with a bolt-on skewer, and you can only access the bolt once you’ve entered a three-letter code.
Check out the video to see how it works…
A front and rear skewer set is priced at €42 (about £35).
You can replace a saddle clamp quick-release bolt with one that uses a combination code system for €22.95 (about £19). You can also get complete combination saddle clamps in various diameters, starting at €25.90 (about £22).
Sphyke do an A-Head stem lock for €24.90 (about £21), and saddle locks for €22.95 (about £19)
The idea is that C3N makes it much harder for anyone to walk off with your wheels or saddle when your bike is locked in a public place. You’re securing the components to the bike without the need to carry an additional cable lock. It reminds us of the Pinhead locking fastener system – although Pinhead uses a key rather than a combination code.
You can buy online through the Sphyke website and you currently get a 20% discount if you buy more than one product. Sphyke are in the process of selecting a limited number of independent retailers in London.
