Hi all,
I normally ride with a pump, using jersey pockets instead of a Camelbak for morning rides. But after losing two Crank Brothers pumps in a month (They seem to like escaping from jersey pockets - I don't know, either) I've decided to try CO2 canisters instead.
I've got a Genuine Innovations Microflate Nano head from a race I did a while back - it was a freebie - but no longer have the canisters. I've looked around, and it seems these canisters (they're threaded) are 'special' in some way.
Is there a source of cheap canisters, or am I better off buying yet another pump? I'd hoped to find my lost pumps on my morning loop (It's only eight miles in total, with a couple of reps, for god's sake) but they never turn up.
