    Just got a new roadbike. This was never an issue for before having always ridden mountain bikes.

    Have handpump for emergencies but just thinking if I was out and about and wanted to pump to full pressure after a puncture and managed to find a garage.

    Is there some kind of conversion device I can get to pump my presta nozzle wheels with a filling station pump (ie schrader style on cars)?

    Those conversion devices work absolutely great; I have them on all my bikes (all Presta.) You need to be a bit careful not to overinflate when using a petrol station pump with a road bike and in my experience the pressure display on Irish-style pumps cannot be trusted so don't rely on it.

    I have seen bicycle tubes being blown apart by garage air hoses twice in the past. Both times it was by kids (well, teenagers) pumping up their own tyres and maybe they just didn't know the risks, but it is worth bearing in mind that a shredded tube (and maybe even a wrecked tyre) is a possibility. Those pumps can give out a lot of air very fast, so I'd expect them to be tricky to use safely.

    There are some decent hand pumps out there that will get to full road tyre pressure fairly quickly (and without the need for the forearms of Governor Arnie!). Or for emergencies you can carry one of the disposable cannisters of CO2 specifically for bikes (like this one). Throw "pump" into the search facility on www.bikeradar.com for lots of mini reviews of various pumps - the Zefal HPX tends to get good reviews but there are smaller alternatives too.

    You can apparently also split the rim which is even more serious but I've been pumping up my bikes with them for decades without incident. You do need to be careful and just give it a very short blast each time.

    I would get a track pump for home use though.
