The Holeshot Fast Flow is Peaty's tubeless valve for rims running sealant. Its patent-pending design moves the valve seal down inside the rim and replaces the usual straight bore with a flared bell-house opening. Air and sealant travel straight into the tire, which Peaty's measures at 110 litres per minute against 54 for a standard Presta valve.
A 7075 aluminum shaft carries a stainless steel core, and every surface is anodized to stop sealant sticking to it. The valve is fully serviceable at home, with a circlip at the base giving access to replaceable seals. Each pair ships with two caps that double as tools, one an e-bike chain lube applicator and one a spoke key.
