CO2 inflators

Have gone to tubular race wheels for the first time (650x probably 21 tires). I haven’t yet used my CO2 inflator with them. Anything I need to know? 1 canister per tire - does that get me to the higher tubular pressures? Any trouble with valve extenders?

Advice please. Thanks,

Deke

A 16 gram will typically get my 700X23 to 100 or 110 psi, depending on how fast (read:sloppy) I’m being.
