I've been cycling in UK, Europe, the Middle East and Africa for nearly 50 years - and I've just discovered that I've been running on under-inflated tyres all this time!
This pump is very good for the price, hence the 5 stars.
It's well made, the gauge is fine as far as I can tell and the adapter that fits onto the valve seems well made and up-to-the-job. The pump works smoothly and with minimum wobble in the moving parts. It works on both presta and schrader valves, so that's good if you have a variety of bikes to maintain. It looks as if it will last for a good few years.
It's the gauge that has me fascinated! I never knew what 80 psi in a tyres felt like. In the past I'd always pumped up the tyres until they felt very firm and didn't bulge too much when I sat on the saddle. Now I have this pump I know what they should be, I'm amazed and a little depressed to imagine the Megajoules of wasted energy I must have expended over the years. Now that my tyres are at the right pressure, it's like having a brand-new bike! It's opened my eyes to what cycling should be like.
If you've never had a pump with a gauge and, like me, you've been using your thumb to guesstimate your tyre pressures, buy one of these pumps, keep your tyres hard and experience cycling anew!
