Product Description

We have had reports from customers that this product does not fit the following products: 1. Older style Halford 12v pumps 2. American Bonaire 12v Pump We have double checked that this presta valve fit Beto brand hand pumps (by buying the pumps ourselves in July 2013) and can confirm that they will fit. The easiest way to fit this product is to keep the pressure lock applied and slide in the valve (which sounds odd but it works). Alternatively you can push the valve into the pump valve with the pressure lock not applied but you will need to apply some pressure and use a screwing action (hopefully that makes sense). As a rule this is a standard sized valve and should fit the vast majority of products.

Bought several different makes of Schrader to Presta adaptors and this one came out on top.
Well machined, good quality adaptor. Seals really well, thicker O ring than others I tried and has a longer thread than others which is useful for using tyre pressure guages.
I am now able to use air compressors at a garage / petrol station which of course don't have Presta valve connections.
Prompt dispatch, fast FREE delivery; £1.70 well spent.
I recommend this one over the others available from my own personal experience.

There's not really much to say for this excellent little gismo. It saved me having to spend upwards of £20 on a new pump for my bike. I put it on and I can use my Dad's compressor to blow up my tyres again. Wooties :)

My bike is a 'Specialised' mountain bike, thought I should mention as I see someone saying that it didn't work for them on their Halfords bike.

For the times you need to (carefully) use a garage airline, car compressor or someone else's pump to fill a Presta valve tyre these are ideal. They have a rubber seal which many others don't giving you a perfectly airtight seal.

This product worked very well and is particularly useful if you want to convert to a schrader valve. It certainly makes inflating the tyre easier and to a better pressure. What you do is simply loosen the presta air valve, screw on this adapter, and then inflate. If you do not loosen the presta air valve you will not be able to inflate the tyre. The presta valve is protected by the adapter so no risk of losing air having loosened the valve.

A Helpful and cheap solution as I can now inflate the tyre using an electric air pump or at the garage.

In cycling terms, this is the best purchase I have ever made! It is the key to taking the back ache out of pumping up presto valved tyres by opening up the job to car electric pumps, and widening the choice of inflations in the event of a puncture. It is tiny into the bargain so easily finds a home in the emergency tool kit I always carry. Quite why I never came across this handy little gadget before, I know not. But, it is now on the indispensuble list. Furthermore, it is very reasonably priced, well made, and delivered promptly. Strongly recommended, with the proviso that caution should be exercised when using this with a garage forecourt airline on bicycle tyres - strictly an emergency measure, as overinflation is only too easy with noisy and potentially dangerous results!

This small and light item makes it much easier to inflate tyres with Presta valves when you have a puncture out on a ride. I found using my quite small hand pump very awkward on a wet and windy day trying to keep it in place on a presta valve. This solves the problem. Good value and arrived quickly too.

When ordering, and being an engineer, I noted that most of these valve adaptors were made from aluminium / zinc die-cast (a low quality, weak material, subject to corrosion). This, on the other hand, is made from solid brass; stronger, precision made & will not corrode. For a few coppers more; you are worth it!

Unfortunatley the adapter failed to work with either of my 2 Halford 12v pumps or my American Bonaire 12v pump. Pumped the bike tyre to 36/38 psi and would go no more. The supplier has been extremely good in offering a free post returns service and will be posting a warning about this as they have had previous issues reported.
