3.0 out of 5 stars Nice features, but not durable, May 9, 2010

This review is from: Zefal Twin Bicycle Tire Gauge (Sports)

I bought three of these about 10 years ago. I have used them sporadically to check tire pressure on autos, trailers, lawnmowers, and bicycles. They have a really nice feature where it holds the reading until you release the pressure.

However, two of the three have died. It's like a seal in the back end of it gives out and then it leaks air constantly. This means that it cannot hold the pressure to give you a reading. So I won't be buying another of these.

5.0 out of 5 stars I don't even remember how many years ago I bought this, but it still works., June 12, 2010

This review is from: Zefal Twin Bicycle Tire Gauge (Sports)

I bought this at Tokyu Hands in Shinjuku, Tokyo, Japan years ago to carry with me while cycling, and I take it with me every time since.

I remember I bought it in Japan, I moved back to the States in 2004, and I had been using it in Japan for at least three years, so let's just say this thing has been serving me well for ten years and tens of thousands of miles. During that ten years I've ridden an average of four days a week / 52 weeks a year--so that's thousands of rides this thing has lasted me. It's also safe to say I've used it at least a hundred times, probably twice that.

And it still works.

If you haven't been using a pressure gauge when inflating your tires, using the old pinch or squeeze method instead, I guarantee your tires are horribly underinflated. Try to correct this without a gauge and they might be horribly overinflated--which can cause them to explode (really, this has happened to me).

Stick it in your pocket, saddle bag, or backpack along with a couple of Pedro's Tire Spoons, a mini pump, and a spare tube and you're ready to be up and rolling after a flat during all those good times cycling without having to end your ride midway, take the bike to a shop, and pay $15 to $20 to have a pro do a bad job of what you should have been able to do better yourself in five minutes on the side of the road or trail.

Note that this gauge is compatible with both Schraeder valves--like the ones that are on your car tires--and Presta--which are those skinny valves that are found only on narrow bicycle wheels. There is a separate 'female' port for each of the two types of valves as well as a button on the end you press to reset the gauge to zero before taking a fresh reading.

The gauge is feather light and packs easily despite its odd shape. I especially like that analogue big dial gauge by comparison to the old popout stick gauge which is relatively difficult to read, or a digital display.

TIP: If you're wondering how much air should be in your tires look at the sidewall of the tire for this information. Every tire--bike, car, tractor, NASA rocket pad, et cetera--has the pressure range and recommendation written on the side of the tire. Don't make the mistake of assuming that the tire pressure depends on the type of vehicle, because it doesn't. It depends on the particular make and model of tire. A typical mountain bike tire for instance will have a recommended pressure range of 50 psi to 65 psi, but some wont go that high while others might be able to take as high as 100 psi; road bike tires typically take 120 psi, and car tires typically take 35 psi. But do yourself the favor of actually reading the pressure recommendation on the side of each tire before pumping.

Bottom Line: If mine ever ends up breaking on me, I'll buy the exact same one again.
