As Jay Leno often comments, in order for new technology to succeed it can't be just good as existing technology, it has to be better.
The Clik system is simply better in every way than presta. I've been cycling for 50 years and I have to put this little valve up there with all the other great equipment improvements. Use Clik one time and you'll be kicking yourself for all the decades spent dealing with the inefficient and troublesome presta system.
Absolutely the best upgrade No more bent or leaking presta valves
I love the Schrader variant but my new rims are too expensive for me to drill out to accept the car valve so I had to get Presta. So when I discovered Clik, I knew I wasn't the only one to think that Presta is an inferior system vs Schrader. Clik offers basically best of both worlds with the extra bonus on top (get it?) with its quick deployment head profile. Thank you for existing! So these caps are overbuilt ove the plastic stock ones plus you can use them as lever to install/remove the core Clik valve.
Exactly as touted these cores, and this system, have eliminated the problems we all dealt with for too long.
After receiving and installing my first set of Clik valves I will never use Presta valves again. Anyone who says Presta valves are fine either hasn’t tried Clik or is just lying. I’m replacing the valves on every bike I have. Also, the adapter works with any standard pump and can be kept in your saddle bag so there’s no concern with compatibility. I expect these to be the new standard in the coming years; it’s just better.
