I use a couple Performance items. Their mini head that easily screws onto my x-lab, and a larger version with a canister holder for training rides.
Threaded/Non-Threaded.
All tops (that I'm aware of) will take threaded cartridges as you simply screw the CO2 canister to the pump head. Non threaded canisters require a canister holder that screws onto the pump head that you put the CO2 catridge in. Basically, non-threaded cartridges are a lot cheaper (pick them up at your local athletic store by the box rather than at the tri store)

Threadless are cheaper..
Threaded are more expensive but nice because you only need a small chuck to attach to the threads and you can inflate. I carry a chuck during races and typically carry a "second wind" inflator in training. The second wind is a CO2 inflator that also is a small hand pump. The hand pump is not the fastest in the world, but it's nice in a pinch if you run out of CO2 or if you want to locate a tube puncture and do a patch while on the road. It also takes both threaded and non-threaded cartridges. Link is here: http://www.performancebike.com/shop/profile.cfm?SKU=16497&subcategory_ID=4362

PJT - is the second wind small enough to keep in my seat bag? good for races and/or training?
what about the Quickshot or the Proflate...?
thanks

The second wind will fit in a medium-sized seat wedge bag and still leave room for a spare tube, levers, etc. It is too long for a smaller wedge. It also includes mounting hardware if you want to place it on your seat tube braze-ons behind the water-bottle mount. You could race with it, I suppose, just make sure you've practiced inflating tires with it before race day. I carry a chuck on race day just because they're so much simpler to use, though if I don't get the fill right on the first try, I know I'll be waiting for tech support.

Just a note...one thing that a lot of people overlook with the chucks.
You have to screw the cartridge on all the way, and then release it a little bit to inflate. You have air flow control through a quick turn of the wrist (assuming your chuck is built the same as all the ones I've seen). Cartridge is cold, but isn't going to damage you.

oh yeah? ...when it's below 45 deg and raining, that little thing can freeze up on the valve stem. gloves or a cloth of some kind are highly advisable as a buffer for your fingers.
i'd definitely take a pump of some kind if you're riding in cold wet weather...
any other weather, no biggie! the tiny little CO2 valves are great for those times!

Personally, when its 45 and raining I am wearing gloves any way :) I use the threaded. Take up less space.

My chuck, which came from Planet Bike (I think) has this little neoprene sleeve that wraps around the cartridge. It great because it keeps you from freezing your hands and keeps the cartridge from loudly banging into stuff when it's in the bag.

I use a small pump for training (Specialized PVO...Presta valve only.) Use a threaded chuck for races.
Neat trick that avoids CO2 mistakes: When you puncture and have to replace the tube it goes easier with a little air in it. Don't use the cartridge. Open the valve stem and blow into it like a baloon. It puffs up just enough to make instalation easier.After it's all together, finish the job with the cart. Works on Presta ONLY!

What CO2 inflation device should I pick up? why the option of threaded / non threaded. thanks
