PRESTACYCLE QUICK CLICK 2 PRESTA HEADQUICK TO CLICKInflation is a very important thing that needs to be done before every ride. If your tires aren't properly inflated, then it can result in lower performance and increased chances of flatting. The Presta Cycle Quick Click 2 Presta Head is designed with a shorter angle which allows room to fit into a wider variety of wheels. It includes the improved Mini Presta Head Gasket which is softer, more durable and gives a better seal along the Presta shaft for any Presta application. It allows high-flow inflation with the valve core removed for seating tires, engages the Presta valve just below the cap threads and requires less insertion, and is safe for all types of Presta valves. Features Made with 6061-T6 alloy which is as strong as brass but 1/3 the weight Compatible with Silca pumps and can be adapted to other pumps with an optional Schrader barb Engages the Presta valve just below the cap threads and requires less insertion | Prestacycle | Quick Click 2 Presta Head Prestaflator Quick-Click 2 Presta Head
