Velotubes Presta Valve Core - 10 Pack

I was told by a bike mechanic to replace the valve cores anytime I add sealant to my mountain bike. I didn't take that advice at first and then my valve cores would get gummed up and bent and leak air when I unscrewed them to add air or get sticky and stuck so I couldn't add air. I just replaced one with this product and I easily added air to my tire and went for a ride the next day. Everything seems to be good. No issues. Now I plan to keep these on hand at all times and replace them more frequently instead of waste time with bent or sticky ones. I also always plan to keep one in my pack when I go for rides.

Good quality valve cores from a recognized company, and at an affordable price.

I had a leaving tube it was leaking at the steam. I didn't realize you could change the valve steams on a presta valve but it worked like a charm and stopped the leak. Cheap fix

They work they way they should. No complaints but no compliments either. Good to have a few spares on you

Swift ship. quality product and fair price

Perfect fit and quality of this valve is what I’d expect an artist using a high end cnc machine would create! Super easy to install and BAM, back up and riding again after a random valve failure I had just riding around my yard testing my compression on my suspension. I have 2 of these in my small saddle bag incase myself or someone else needs ones. Great price for the pack! Again the fit and finish is second to none. I could look at these all day as they’re so perfect.

Everything as promised

Works like they should, good open airflow, no leak closed.

Quick delivery. Valve cores fit the tubeless valves perfectly. Three of them have been in use for almost two cycling seasons without any issue at all. Great to have a 10 pack so always a few extra around as they do get gummed up with sealant and are hard to clean. For the price, just replace the gummed up core.

Would do the job

If you are a mountain biker you should carry one. I went to adjust tire pressure last month and when I unscrewed the cap, the value core flew out never to be found again (LOL). Just what I needed.

Exactly what I needed at a really good price. Delivery was very quick so didn't miss anytime on the bike.

Works as it should. Looks like a quality product. Inclusion of a plastic .25 instal/removal tool would have earned the last star.
