These are essential if you run your tyres tubeless.
The kit comes with a tool to clean out the puncture, 5 gummy plugs, a tool for inserting them, some glue and a wee knife for tidying up.
Maybe you'll be lucky and never need them, but there's a good chance someone you're riding with will, then you'll save the day!
