FriendaValve Core Remover Tool Kit Bicycle Valve Core Tightening Tool and 10 Pieces Cores Brass for Bike Bicycle Tire Application

Just replaced some old cores with these. They seem solid and went in smoothly. No issues. Tool is also nice. Would buy again.

Good quality!

As soon as I removed my first valve core, the metal on the remover started to chip. It looks cosmetic but don’t expect the color to stay. Otherwise, it works as intended and is essential in your saddle bag.

This worked well for me. I have tubular deep-rimmed wheels and I was dreading having to change the tire due to a slow leak. After checking the tire, it seemed the leak was the valve itself. I ordered these cores, replaced the possibly faulty one in the hopes it would fix the leak. It did! The kit came with clear instructions and a little tool to help with the replacement. Great little kit!

I have two left thumbs sometimes.Have you ever removed a valve core on side of road to repair a flat only to loose valve core in the process. No more my friends. Always be prepared. Replacement cores take very little space and you get a cool color coordinated tool for cheap

I just got new tires on my bike and unfortunately the FIRST time i went to add air for a different terrain type i found my valve core clogged. I bought this and watched a video, took all of 30 seconds and I now know how to do one more thing on my bike by myself.

Very good set

Small enough to pack for rides. Works great!

Cores stuck? Replace them!
