Big improvement over the regular valves. Faster to pump the air in, cleaner, and less air slippage
I've made the switch from Presta to Clik cores after having first tried another brand's adapters that would unscrew too easily from the stem. These Clik cores are nice and solid. My only complaint is that it's a bit harder to let air out with this design, and some of my pump nozzles don't like it, including my electric micropump, but that's what the Clik adapters are for. The nozzles that do work work VERY well. Pump nozzles can be pretty wobbly and insecure feeling on presta cores.
Game changer! So much better than traditional presta valves!
Pop this in your existing pump, and easily remove it if you need to fill a Schrader tire. No pump head replacement required! I still ended up ordering the right angle adapter so I can use this little guy to carry on the bike.
