e*thirteen Presta Quickfill Tubeless Valves

Quick Fill Presta Tubeless Valves for 16-24mm Depth Rims - Black

Quick Fill Presta Tubeless Valves have a unique 4-part design, with a one-of-a-kind valve core carrier, which can be conveniently removed by hand and without removing the valve core. The oversized valve stem, which fits 100ml sealant bottle nozzles perfectly for mess-free sealant injection, without breaking the tire bead. The valve stem port (without the need to house a valve core), has an exceptionally large inner diameter, providing a cross-sectional area increase of 45% over our Gen 1 Valves, and about 10% over new "Filless" competitor valves. This means higher airflow and less chance of clogging. A CNC alloy and rubber base nut seals snugly with all major rim brands, and works with tricky tire inserts such as Cushcore.

Two Sizes: 16-24mm rim depth (fits most MTB rims) / 23-31mm rim depth (deep-well rims)

Valve stem port with 3.5mm diameter provides high air flow compared with Gen 1 or competitor brands

Allows sealant injection direct from the bottle, without breaking tire bead, and without passing through the valve core, for less clogging.
