The upgrade kit integrates FIDLOCK’s innovative magnetic winch handle and ratchet system to ensure your bike always stays secure. Combine it with your original CLUG to transform it into a CLUG PRO. Simply replace the original clipper with the upgrade kit clipper (which has a seamlessly integrated magnetic FIDLOCK winch) and re-fit using the original wall anchors and screws. The cord length can be tailored to your tyre and rim combination, the ratchet will give you the perfect fit every time and the winch’s interlocking teeth give it extraordinary strength. Engineered to hold up to 30kg once the winch is magnetically locked into place, the winch and ratchet system gives you total peace of mind that your bike will remain rock solid even after a hard knock or if your tyres deflate during long-term storage.
