Do not buy

Have used it only twice and already the treading is slipping and the air leaks. Absolutely not happy, fyi I have used only the presta valve.

Hello Sushant,

Thank you for reviewing our product, as it help us to improve our product, please take the product to our nearest Decathlon store and explain the issue to our team and they help you to get exchanged if you are not happy with it. but just to clarify this kind of threading issues happen some time if don't align the valve and tube properly.





This comes handy to angle ur pump. Can combine with the mini/portable handpump.
