Tubeless tyres are now widely accepted to be the best choice for gravel bikes, mountain bikes and even road bikes; but whilst tubeless technology has come a long way in the last decade, tubeless valves remain one area that has been ripe for improvement. Tubeless bicycle tyre set-ups usually use a Presta style valve, with a removable valve core to allow you to inject tubeless sealant into the tyre without removing the tyre from the rim. Yet, Presta valves have two disadvantages: First, their relatively small valve opening reduces the airflow that can be pumped into the tyre in one go, this is problematic when you want a large whoosh of air to 'pop' the tyre bead onto the rim when seating tubeless tyres. The second disadvantage is that tubeless sealant tends to clog up the delicate valve core, leading to problems inflating and deflating the tyre. Muc-Off have a solution to the downfalls of Presta valves, with their new Muc-Off Big Bore Tubeless Valves. Designed to maximise a...
