Need adapter to fit to a footpump and blow up a Presta valve

RSV_Ecosse

Hi folks,

I've just knackered my track pump. Can't complain as it was a cheap Tesco job and has lasted years. Planned a run tomorrow but need to check my tyre pressures and make sure they are good to go. I've got vouchers to spend from Xmas for the Edinburgh Bike Co-op so intend ordering a decent track pump from there but in the meantime, I wanted to see if I could use my double barrel foot pump?. I need a valve adapter of some sort as it is a standard foot pump ( used to blow car and motorbike tyres up ) but I'm not sure what adapter to go for. Halfrauds have two, one that says its a Presta adapter and one a Schrader adapter. What one do I need to fit the foot pump properly that will enable me to connect to a Presta valve? :-

You would think it would be the Presta adapter, but upon zooming in on the image, the valve end looks a bit strange?. Or is it just me being daft?.

Ta.

taff..

you need something like this



presta-schrader adaptor

oh, the last time I used a foot pump it fell apart at about 90psi :roll:

The foot pump fell apart?. :shock:

Is that a common thing?. The alternative I have is use my mini pump but I'll be there all week trying to get 120psi into the tube. Or I suppose I could screw the adapter onto the valve and take the bike to a garage to blow up using their compressor powered one?. Might end in tears though!.

Yup - that Presta - Scrader adaptor is what you want, however its bit of a fag to get a good seal and even more of a fag to get a good pressure reading.

I carry one around as an emergency back up.

Why not just £15/20 and get a track pump from CRC/Wiggle/etc that'll do the job properly?

taff..

aye, I think foot pumps are designed for cars that normally run at 30-40psi not a 120psi bicycle tyre, forecourt compressors only go up to about 80psi these days

As I said, got vouchers for Edin Bike Co-op and I'm just about to splash £30 on their Revolution Air Pro track pump. Might as well use the vouchers rather than cash in another shop ( tight Scottish git, me ). The valve adapter was really just to allow me to get out tomorrow for a run as the tyres need pumped up since my last ride. 8)

Your footpump is unlikely to be rated at road bike tyre pressures.

You are most probably correct. Looks like I'll be getting a bit of arm exercise tomorrow then, I'll try and use my mini pump.

Will be good practise so you know what to expect if you get a p******* when your out
