Made from high quality, lightweight and high strength 7075 aluminium, Peaty's MK2 tubeless valves fit most tubeless setups from MTB to road and cyclocross, including carbon, enduro and DH rims. The unique x-cut base is designed for use with all tyre inlays. The channels machined into the valve base allow air and sealant to pass through when the inlays are pressed against them. Unlike most other valves compatible with inlays, Peaty's valves have a "straight-through" design so there is no reduction in sealant or airflow when tyre inserts are not used. Installation couldn't be easier. Integrated O-rings prevent the lock rings from scratching your precious rims and large soft rubber bottoms easily provide an airtight seal. Designed by riders for riders. Peaty's valves come standard with an integrated cap for removing the valve core and a spoke wrench cap (for standard 3.4mm diameter spoke nipples). This makes tightening loose spokes and topping up sealant a breeze, whether in the workshop or on the race tracks.
