Presta to Schrader Aluminium Bike Valve Adaptor Adapter Converter with o-ring Seal

Two come in the pack. You one was missing its o-ring seal and had to be thrown in the bin.

Does the job but long delivery wait.

They arrived and were what I’d ordered

Bought this to be able to use my standard bicycle-pump to pump up the tubes on my bicycle that has the newer type of valve installed.While I've been able to fit the adapter onto the tube valve, I was not successful in pumping air into the bike tube. Not really sure if there's some trick to using it, or it was defective.Anyways, considering I paid just around a couple of quid (can't remember the exact amount) to buy this, it's just a minor disappointment. Though I still need a solution for my problem - to fill air into the bike tube.

Good value , be gentle with these as no doubt the alloy threads will strip / cross thread very easily. They work ok,now I can use the car foot pump to inflate my push bike tyres.

Looks good, slightly smaller than my plastic original (means that it is a loose fit in the pumps storage area), but took a long time to come. Very good price.

Very cheap plastic. I’m sure they will do the job but as my compressor gets quite hot I would imagine they are only good for one use. That said at the price they are still good value.

Does what it needs to do. Just need to be careful on how tight you screw it on to get the right placement for the pump without deflating your tyre.
