The Presta valve is an outdated standard so the Clik alternative resolved that issue. To my surprise the adapter in combination with the Clik valves brought my E-Pump back to relevance. The E-Pump was made for Schrader valves so I had to use an adapter for Presta valves, which was always a hassle. The Clik valve+adapter resolved that issue and the combo makes pre-ride pressure top-ups quick and easy. The only issue I have experienced is that the Clik adapter don't work with my Lezyne Road Drive Hand Pump, although my spares have Presta valves so its not a deal breaker.
