Traditional Presta valves were designed for tubes, not tubeless setups. Sealant can clog them and restrict airflow, making tyre installation slow and messy.
Peaty’s Holeshot Fast Flow valves are engineered specifically for modern tubeless systems, improving airflow and preventing common valve issues.

Please note - Image will show the 42mm length if a colour other than black is selected, if selected the 60mm will be supplied (Image of 60mm length can be seen in Black)

After over 2 years of development and 27 design iterations, every detail has been optimised for maximum performance. The valve seal is relocated to the base of the 7075 aluminium stem, creating a larger seal and reducing airflow restrictions so air and sealant move directly into the tyre.

• 200% greater airflow than a standard Presta valve
• Seats tyres faster with higher air volume
• Sealant can be added without removing the valve core
• No special tools, compressors, or pumps required
• Fail-Safe Racing Design
• The patent-pending design places the valve seal inside the rim, protecting it from impacts or damage. This ensures the valve remains airtight even if the shaft is struck.
• The internal cage also makes the valve compatible with all rim inserts.

Each set includes functional valve caps:

• E-Bike Lube Cap – prevents crank spider spin
• Spoke Key Cap – for quick trail-side adjustments
