Peaty's MK2 tubeless valves replace the stock valves in a tubeless wheelset and give sealant a clear path into the tire. The distinguishing feature is a four way x-cut base, which keeps air and sealant moving even when a tire insert presses against it. With no insert fitted, the straight through bore flows without restriction.
Each valve is built from anodized 7075 aluminium and fits rims with valve holes sized for 6mm Presta valves. Both caps do double duty. One carries a spoke key for standard 3.4mm nipples, the other removes the valve core so sealant can be topped up. An O-ring, lock nut and replaceable rubber base complete the set, backed by Peaty's Valves for Life guarantee.
