Plug holes in your tubeless tyres by carrying this nifty puncture plugs refill kit from Muc-off. Designed for road, mountain bike or gravel tyres, simply insert a plug into punctures that are too large for the sealant to close off on its own. There are three different sizes, thin,medium or thick, so you can choose the right plug for the situation and be rolling again in a flash without the need to give up on your tubeless setup by sticking in an inner tube.
