XLAB Speed Chuck CO2 Inflator

The XLAB Speed Chuck CO2 Inflator is a compact, no-fuss tool built for one job: getting you back on the road fast. Compatible with both Presta and Schrader valves, it works with threaded CO2 cartridges and inflates a tyre from flat to full in roughly a second. The flow is modulated, so you can dial in the amount of air rather than dumping the entire cartridge at once — a small detail that matters when you're mid-race and working under pressure.

Lightweight enough to disappear into a saddle bag or jersey pocket, the Speed Chuck adds almost no bulk to your kit. A straightforward push-to-inflate mechanism means no fiddling with valves or threading under stress. For triathletes and road riders who carry CO2 as their primary flat repair, it's a reliable, well-thought-out inflator from a brand that knows race-day kit.
