Do you Co2? Birzman infinite co2?

[Kevoffthetee]

Have made the switch? I'm thinking of trying the Birzman Infinite Co2 as it is a dual pump which attaches behind the bottle cage, meaning I don't need a bigger saddle bag.

I have a hand pump plus Co2 cartridges & tyre inflator.
Haven't used the Co2 yet, got more for inflating tyres when out on a ride.
