I'm sure there's a trick to it, refilling your tires with those little valves and CO2 cartridges, but I never found it. It was always a crapshoot how much air I could get from that little thing into the tire. Probably it was a matter of technique. I've been trying to start with myself as the error, then seek alternate explanations.
So I started carrying a Lezyne Road Drive hand pump, which is awesome (and we still sell), btw. I added one of the in-line pressure gauges to it, and it'll re-inflate your tire on the roadside to 100 pounds of pressure ... with effort. But you look sorta silly. I mean, it works, so it's got that going for it, which is nice, but wouldn't it be better if we could salvage some dignity?
Last week, Fred showed me these ... the Shiny Object.
No, that's really its name. Here's its cheesy marketing copy:
The Shiny Object™ CO2 inflator is made of indestructible oh-so-shiny alloy and fits on both Presta and Schrader valves. Its control knob easily regulates how fast the CO2 is released, making flats a breeze to fix.
Available as inflator only or inflator with vegetable tanned leather sleeve and 16 g CO2 cartridge.
You had me at "control knob."
These babies retail for $19. Come in and get some (and also probably a CO2 cartridge or two). Sure, we also have other pumps, as well as all manner of bike parts, bar tapes, hydration solutions, apparel and, oh yeah, bikes. Have you seen the new Focus Izalco Maxes yet?
