Each lightweight and durable set contains everything you need to get back riding when you're stuck battling a hole that's just not sealing: a stainless steel 2-in-1 puncture plug reamer tool, a variety of different sized tyre worms and a trimming knife. Made from ultra durable 6061 aluminium, the Tubeless Puncture Plugs are small and lightweight but super tough - perfect for tackling even the peskiest of punctures! These nifty tools fit tidily into your bars, secured with just a 4mm Allen key.
