|CO2 or Frame Pump Recomendations???||mtbcyclist|
Jan 17, 2004 3:01 PM
|Hey people. Used to ride a Lemond Tourmalet which was designed to hold a frame pump which I used. I just upgraded to Litespeed Hyperion (sweet ride) which is not designed for a frame pump.
Now I have to go buy a new emergency tire inflation system. It looks like CO2 is the way to go if you have a non standard frame (can't hold a frame pump). I have never used CO2 and wonder how well they work and how easy are they to use. Can anybody make recomendations on brands? Performance bikes has several nice looking ones on sale, but I have no idea how they work.
Any help would be much appreicated. Thanks!

|I switched to CO2 last summer and never looked back. A ten second shot from the inflator and I am on my way. My old hand pump took forever and never seemed to inflate to what I wanted anyway. I use the Innovations Ultraflate Pro which gives me great control on inflation. I ride with a group of five who all use the same cartridges.We all carry one cart., a tube, and the inflator. Be sure to get the 16 gram which should easily get you to a buck twenty on the pressure.|

|Never got that high with a 16g.

|Buy the cheapest valve you can buy (don't buy the fancy ones with handles and stuff) and get your cartridges at Wal-Mart. Much cheaper.
A 16g cartridge will get you close to 100 psi in a 700x23. Then you can ride home and put real air in, because the CO2 will deflate.

|I carry a Blackburn frame pump on my 'cross bikes (only one of which--'00 JtS--has a peg), and I've never lost it once, even on rough fire roads and singletrack. Just get the right size pump and the spring will keep it in place.|

|co2 has its place in races and the like, but for every day commuting / messengering / enjoyment i don't see any reason to use them over a hand pump. a good quality hand pump will inflate a tire in a minute or two, keep your heart rate up, leave nothing behind in waste, and doesn't have an expense attached to it every time you inflate a tube. co2 seems like a waste if you have a slow leak and just need to slightly repressurize once or twice on your way home to fix the problem. one of my favorite elements of cycling is the simplicity and autonomy of being able to fix most problems on the road any time they occur - i'd feel defeated if i had three flats on a particularly bad day, had run out of co2 cartridges and had to walk the bike to my destination. good old manual inflation for me every time.|

|had to pump MTB tire yesterday (Python 2.0) and two (2) 12g cartriges didn't get even close to 30psi. Granted it is high volume tire, and it was cold 22F.
I'd suggest to use mini pump to pump tire to ~10-20psi and then top off with CO2. Innovations make a mini-pump/CO2 combo, check it out. If you wanna stay with frame pump there're plastic pegs you can fit on bike, should be 2-4$ in LBS good luck

|I switched to co2 a couple of years ago. At that time I had trouble getting enough air into my tires mounted on Rolf rims without snapping the valve stems.
The most I can get into a 700x23 tire with a 12g cartridge is about 90 pounds, which is fine. I have checked my psi when I have got home with a guage and sometimes all I can get in is 83 pounds. I have never had a problem completing a ride with co2.
The 12g cartridges can be purchased in lots of 25 for around $12-$15 at places such as Kmart or Wallmart. It is the same cartridge that is used for air/paint/pellet guns and such.
You just have to get the knack of using co2 as if you use it incorrectly (such as not holding the applicator at a 90o angle) the air will freeze upon application and not go into the tube.
But (there is always a but)...if you can mount a full length frame pump such as a Silca, Blackburn, or Zefal; one of these will never let you down. You have to pack a couple of cartridges of c02 and if you run out (I had 5 flats on one ride once) you have no inflation system. I pack a small Torelli mini pump as a back up.
If you switch to co2 practice using a couple of cartriges in your garage so you know exactly how to use it. When I made the switch to co2 my flats came to nil and I have to remember how to use it.
Remember it's about what works for you...some of the mini pumps work swell also.....

|It is possible to improvise a pump peg using an old Zefal clamp designed for a seat tube. I tried minipumps for awhile, didn't like them, and went back to my trusty Zefal HPx on both my road bikes. The clamp shown with the pump has not been modified yet, I later cut it off the peg and ground it down to fit the pump head better...and look btter too....|

|this one has been cut down and ground to fit pump better...|
|Thanks guys! I decide on CO2.||mtbcyclist|

|Went to Perfomance and got a good system for $14.99 on sale. When it gets here I will be off to Wallyworld (aka Walmart) to pick up some CO2 cartridges. I decided I did not want to clutter up the beautiful litespeed frame with a pump. Thanks for the info as it helped me decide.|

|Get one that you can regulate. I use an Ultraflate. You can also use one of these http://www.performancebike.com/shop/cboProfile.cfm?SKU=3023
to mount a frame pump to almost any cycle.
