Foot Pumps?

    Any recommendations on a foot pump? All I can find are pumps that max. out at 100Psi and state that their gauge is for "guidance only". For road use I would prefer to keep the tyres closer to 110/120Psi but have to use a calibrated car pump for this - i have come across double cylinder one by Draper (€24) but you have to buy a separate tyre pressure reader for accuracy, another one by Michellin (costs almost €40 and sales guy said gauge on this is accurate but still maxed out at 100Psi)....

    Footpumps are no good for high pressures. They are designed to shift a resonable amount of air from a small stroke. This requires a large diameter plunger, this makes them unsuitable for the high pressures that road/racing tyres need.

    I use a footpump for my max 80PSI tyres, it can still handle that, but it already takes an uncomfortable amount of force at that pressure. Add a second cylinder and that problem magnifies by a factor 2.

    Bicycle track pumps use small diameter plungers and a long stroke, that design allows greater pressures. They pump less air, but that isn't an issue for road/racing tyres.

    Many gauges found on pumps will be too inaccurate to rely upon. With a presta > schader adaptor you can use a digital pressure gauge for shrader valves. That should allow you to get a good feel for the deviation of a gauge on a pump.

    After recommendations for track pumps on this forum, I bought one. Wow, an unbelievable improvement over my small frame mounted one.
    It pumps really quickly. I carry the small one for fixing issues on the go.

    Same as daymobrew. Have a mini for the quick fix on the go and the joe blow track pump for filling up at home. Since I often go for a few months before getting home again, its worth my while having a good mini.

    Lidl are selling track pumps this week for €7.99. They went on sale on Monday. Very good value for money
