Nukeproof Horizon tubeless repair kit features a machined alloy tool, which doubles up as a storage capsule and houses 5x 1.5mm plugs and 5x 3.5mm plugs for repairing holes and punctures in tubeless tyres. Weighing only 50g, it is super light and easy to carry and pack away in your backpack as you ride. Plus, the tool capsule doubles up as a handle for the plug insertion tool and even has some extra space inside for storing a pair of powerlinks for your chain.
The plugs are super tacky so do not require you to use additional glue. Spare plugs are available here.
