Unless you need to air down your tires on the trail all the time, there’s zero downsides to these. They fix every single problem with traditional presta valves. The new valves are very high quality, as well as all the other components in the kit. I’ll be running this on all my future bikes.
Been using for a few weeks now, definitely like them, faster than old presta, easy to work with
The gauge functions well, providing a quick readout. Gauge must be pressed on during use and will not "click" into place. However, the bleed function does not work well - the pressure readout does not update while bleeding, instead holding the highest value initially measured, despite the decreasing pressure. Pressure readout must be manually updated after each bleed action by re-pressing the "on/off" button. A better design would be a "tune" mode, where the displayed value is continuously updated. For this reason I would recommend the manual/analog gauge instead, and I wish I had bought that instead.
Additionally, the supplied battery was dead within a week of use.
Work just as promised and can’t expect ever going back to presta.
Love 'em! No stems to unscrew. No pump levers to throw. Just pop the pump on and off that simple. Air goes in easy with minimal loss removing the pump head.
