I got a Topeak SmartGauge D2. I use it for everything from bike tires, to fork pressure to car tires.
It's brilliant.
Not to hijack the thread, but I have a question about gauges and pumps, and I was going to post a thread about it, but I thought I'd ask here…
I wanted to get a bit more precision out of airing up my tires, so I picked up a Topeak SmartGauge D2. Now I'm more confused than ever. I never quite know what to go with as there's an 8.5 psi difference between my pump (Specialized AirTool Pro) and the gauge. For example, if I pump up my tires to 30 psi according to my floor pump and then immediately put the gauge on, I'm told that they are 21.5 psi… Not sure which one to trust…
I guess if I'm not mashing my rims on every rock, it doesn't really matter, but I'm a bit obsessive about stuff, so having an 8.5 psi difference between two tools is driving me up the wall…
Ride, don't slide.
