Bike Valve Core Repair Kit, 10 Pcs Presta Valve Core with 3 Pcs Presta Valve Adapter, Replacement Brass Tubeless Core Valve and Inflate Tire Converter Tools Set for Cycling MTB Road Bicycle Tube Pump

Little did I know about presta and Shrader valves before I tried inflating my uncles bike tyres.My pump worked well on the Shrader and when attempting the Presta I accidentally flattened his tyre.After learning the difference I checked my own bike to find that my own Shrader pump is useless for my two Presta wheels. These little adapters have been a great help and now my tyres are better than ever. They work great and look relatively aesthetic.

Having the ability to convert a Presta valve to a Schrader value is such a useful feature as I find Presta valves to be annoying, the flexibility and choice are great as you’ll normally have a pump that is more than likely have a Schrader valve rather than the Presta.The overall build quality is good too and for £6.99 you get 10 pieces, which in my opinion represent great value.

These core are much better that the previous cores l purchased. Would have to refill my bike tires very week due to leakage, not with these ones. The seals are much thicker than the cheap cores and seal much better. It has been a month without having to refill my bike tires.

Bought wrong amount by mistake, overall looks great through the packaging. A photo of what you'll receive, mine came a little bit banged up, ,some holes forming in bag, but OK.

Great quality! Good amount of product for the price.

I got this product to replace the valve cores in my tubeless tires. The product arrived as described with the correct number of core replacements and adapters. The valve core threaded into my existing valve stems without any problems. It's a great price and worked great, overall 5/5 stars.

For anyone who uses Stans NoTubes or Slime sealants having additions valve cores is a must.I have always ridden Presta inner tubes whether it be on my road bike or mountain bike.I recently got into the e-bike craze and bought my first e-bike. I upgraded the stock cheap heavy tyres and inner tubes to Presta. Now I can add tyre sealent to that bike too.The valve adapters is a huge plus. Saw someone with a flat once at a gas station and he couldn't use the air pump because of course they have Schrader attachment. I now keep one of them attached to my Presta stem acting like a cap so that I never get into same situation that guy with the flat did.
