CBO Presta Valve Core

new valve core fit right in the valve no problem. I didn’t know I could even buy such a part! Fixed my flat, just like that. I highly recommend CBO they come through when you need them.

This is an excellent value for valve cores. It is great having these on hand for when my cores get gunked up with sealant. It is so much easier to simply swap it out for a new one. I do keep the old cores on hand for cleaning for future use when and if I run out of these. They fit well and do the job.

Have not used yet. Expect them to hold pressure. Long ride insurance with little weight penalty
