Planet Bike Adds Two-Pack 25g Threaded CO2 Cartridge, Doubles Your Pressure
File under small news: Planet Bike’s 25g CO2 cartridge now comes in two-packs, saving you a bit of change if you need a couple oversized inflators. The 25g cartridge claims to fill a 29er mountain bike tire to 45psi and a cyclocross tire to 80psi. Yes, that’s a lot of air. Er, carbon dioxide. Available now on their website.
