    What do you use for flats CO2 or Pump? 29r

    What do you guys use when your racing CO2 or a pump? I usually have a Big air strapped to my seat post. I have yet to use it. But a friend of mine had to and he told me its slow not like a shot of CO2. I watched the Spec. videos from Cape Epic and they had CO2 cartridges strapped to the top tube. I'm guessing they were 20g. I am wondering if carrying 2 of them would be better then the Big Air for a 29r.

    Big CO2 cartridges during a race, pump the rest of the time. CO2 is quick, but the big ones aren't light!

    I've also heard very mixed reviews on the Big Air things, but have no first hand experience.

    I skip the Big Air. It's light but doesn't have the "pop" of a CO2 cartridge.

    It is the easiest one to get past the TSA, though.



    I carry at least one 25 gram cartridge.



    This one is punctured and ready to roll. The thinking being, I'll blow it hoping to give the tubeless juice a chance to save the day.

    For most endurance type events, I roll with two.

    This mainly. Pump as well during a race if I'll be in the middle of nowhere or there are long stretches between aid stations.

    Yep. Depends on the situation of course. If it's a lap race where I'm never more than a 40-minute walk from camp, leaving the pump behind is an option, but...

    Murphy's Law dictates that if all you have is a CO2, and you are far from any other source of pressurized atmosphere, you'll get one more flat than you have cartridges. At least some day this will happen (Murphy would suggest the day in question should be very cold and wet, or that nightfall is near and you also have no lights).

    Nice to have a CO2, especially if you run tubeless and would like to have at least the option to re-seat the bead should all your air burp out. But a pump is the gift that keeps on giving if multiple flats are your destiny.

    Nice awesome strap. I run a back one with a tube multi tool and tire levers. I guess I should say I run a pump when I'm not racing. I haven't thought about trying to reseat a tubeless tire. I just put a tube in and go.
