If you’ve ever struggled to seat a tubeless tyre, it’s probably not the tyre or the pump -  it’s the valve.

Holeshot’s Fast Flow design relocates the valve mechanism inside the rim, allowing air and sealant to pass directly into the tyre - FAST! The result is easier tyre seating, no sealant clog, lower maintenance and precise, micro-adjustable pressure control.

High flow, less faff.
