Most ‘screwdriver and rubber strip’ based tubeless repair systems are a real faff to get to work and potentially damage your tyre even more. That makes the unique Dynaplug system even more of a joy to use on the trail.


Most kits make you push a folded rubber strip through the tyre hole with a cleft screwdriver like a downsized version of car/motorbike kits. That often makes a bigger hole and involves a real fight to get the rubber strip in the tool only for it to pull straight out again still attached so you have to poke and fudge around to get a seal. Instead, Dynaplugs fit a pointed ‘bullet’ to the end of a viscoelastic impregnated strip that stays sticky and fresh inside the ‘insertion tube’. 

The anodised alloy £59.99 ’MegaPill’ tested here includes five standard plugs plus a small cleaning brush for cleaning the insertion tubes before refilling, a tapered air stopper and a tiny plastic-handled knife for trimming the rubber plug tail or microscopic cooking. There’s also a Micro Pro using the same metal canister and contents but with only two insertion tubes for £49.99, a plastic Megaplugger with three normal plugs and two oversized Megaplugs (£29.99). Minimalist weight watchers will want the 23g £34.99 Dynaplug Racer which has a ready to go Megaplug in one end, a standard plug in the other and two spare plugs in the anodised alloy body. The £19.99 Carbon Ultralite isn’t actually carbon but does come with four standard plugs, a cleaning brush and an insertion tube is probably the best value kit tho. Standard plugs are £8.99 for four, while Megaplugs are £9.99 for three.

While it took years for the small US company behind the idea to perfect, actually using Dynaplug couldn’t be easier. Just thread the tube into the handle (they come with one pre-installed) push through the hole, the brass head catches inside, you pull out the tool, rotate the tyre to get the sealant to fill any small gaps and you’re good to go. If you need to plug a bigger hole, just fold the tail over and press it down to glue in place and/or stick another plug alongside it. Alternatively, get the Megaplugger which puts several strips behind a fatter head. Either way, the head holds the plug in place indefinitely and we’ve used it on everything from enduro tyres to lightweight road tyres with 100 per cent first-time success.


Well packaged in a range of options, with an excellent user-friendly design that we’ve had an instant, 100 per cent permanent repair record from on all sorts of tyres. It’s more expensive than normal kits, but the fact it works far better makes the price well worth paying with only Stans Dart potentially coming close but we’ve not actually tried that outside a trade show yet.
