Peatys Peatys HoleShot Fast Flow Tubeless Valves 80mm Presta for Road Bike MTB Mountain Bike Cycling

The Peaty's HoleShot Fast Flow Tubeless Valves - 80mm are engineered for riders using deeper profile rims who demand faster inflation, improved sealant flow and dependable tubeless performance. Featuring Peaty's patent-pending Bell House design, the valve mechanism is relocated to the base of the stem to maximise airflow while virtually eliminating valve blockages caused by dried sealant.Designed for road, gravel and mountain bikes, the Fast Flow system delivers up to 200% more airflow than a conventional Mk2 Presta valve. The increased air volume helps seat stubborn tubeless tyres more easily using a standard floor pump, reducing the need for an air compressor.Bell House High-Flow DesignUnlike conventional tubeless valves, the internal sealing mechanism sits inside the rim instead of at the top of the valve. This opens a much larger air passage, allowing air and sealant to flow freely for faster inflation and improved reliability.200% More AirflowThe enlarged internal air channel significantly improves airflow compared to standard Presta valves, making tubeless tyre installation quicker and helping stubborn tyre beads seat with less effort.Anti-Clog Valve SystemSealant flows around the valve mechanism rather than directly through it, dramatically reducing the chance of dried sealant clogging the valve. This ensures easier inflation, more accurate pressure checks and less ongoing maintenance.Compatible with Tyre InsertsThe specially engineered valve cage allows unrestricted airflow even when using tyre inserts, ensuring sealant and air can circulate efficiently throughout the tyre.Premium MaterialsManufactured from lightweight 7075 anodised aluminium with a durable stainless steel valve core, the Fast Flow valves deliver exceptional strength, corrosion resistance and long-lasting performance while weighing just 14g per pair.Integrated Multi-Tool Valve CapsEach valve includes Peaty's signature multi-function valve caps featuring a spoke key and an E-bike chain lubrication tool, adding practical workshop and trailside functionality without extra weight.
