I would go for the pump as you know you`ll always be able to inflate the tire.What happens if the Co2 inflator stops working or if you get more than one puncture in a ride (seriously unlucky but could happen)

I carry (1) CO2 and one of the little micro pumps that fits in a jersey pocket just in case. When I get the second puncture I'm flipping open the cell phone anyway.

Pump. I don't get rides home in a car (last one was 1995).

I went with a frame pump.

I have had two pumps for my bike and now use CO2 entirely for roadside repairs. I had a difficult time getting to 120 psi with the frame pump. The other pump is the only pump I would ever consider using now which is the Topeak Road Morph. You can get to 120 psi with it but it didn't fit easily on my new bike frame since I didn't want to hang it from the top tube.

I now carry the Genuine Innovation Air Chuck SL which weighs 21 grams. I carry it with 3 CO2 cartridges which weighs slightly less than my Road Morph and it is much easier to use since it will inflate a tire in about 3 seconds.

They also make small pumps that do both - inject co2 and also serve as a regular pump if you need it.

C02. If you've ever had to change (multiple) flats in cold weather, you know why. The faster you can get the tire up to pressure, the better. I carry extra cartridges, especially in wet winter when debris sticks to the tire.

I switched from a hand pump tp C02 after getting multiple flats in front and rear on the same ride in 20 degree weather. I also got tire levers with a steel core after snapping a couple of thin plastic levers in the cold.

It's up for an hour and Botto didn't tell you to use the search function. He must be sleeping in late..

If you are asking this question, I would recommend a frame pump.

yea i think ill stick with the frame pump but might test out the Co2 inflators

On a training ride or commute: both. CO2 for the first one gets me back on the road quickly and gives me a chance to catch the group or make it to the office on time. If there's a second, I'm going to miss the group or be late, so I might as well take my time. You didn't ask but I carry a tube and a patch kit for the same reason.

Don't mind unlucky. I've had a commute day when I've gotten one flat on the way in to work and two on the way back. I was down to patches.

CO2 is nice on group rides because it is fast. Just be extra cautious to make sure your tire is seated in the rim. The cartridge inflates the tire so fast that if the bead is slightly out of wack, the tire won't seat. So, inflate just a little bit, go around the tire to make sure the bead is seated properly, then inflate to full.

Myself, I always carry just a pump. I don't like the wasteful aspect of CO2 with the one-use throwaway metal cartridges. But if it's pouring down rain and everyone's shivering, waiting for you to finish fixing the flat, it's hard to argue against CO2 inflators.

I just grab another bike off my follow car.

Strap this on, but seriously, co2 is the way to go. The flat usually occurs in inclement weather, just before dark, or when its cold.

Those of you that use a pump 1) what kind/model 2) Where do you keep it on rides? I can see putting it in a jersey pocket but not on my frame which is a Cervelo s1.

Thanks

Zefal. Specialized just came out with a new one that looks nice. Have yet to try it though. Most seem to like zefal or the morph..

I carry this same setup with Park glue-less patches. I've never had more flats than I could repair with this setup and it's much lighter than carrying a frame pump. My other issue is that having several road bikes, I just put the saddle pack on whichever bike I'm riding instead of having to worry about buying multiple frame pumps. To each his own though. I like Co2 much better than carrying a pump.

CO2's great, but I always carry a pump as backup.

The best solution is to carry both.

I carry 2 CO2 (16gr.) cartridges and a Topeak Al Micro Rocket pump.

ALSO, a spare tube and a number of stick-on patches.

This covers just about every situation and doesn't incur a large cost in weight.

Sometimes CO2 is best, like when it's raining, or you are in a bad part of town, or there's a mean-looking dog watching you.

I carry the Micro Rocket in my seat tube, along with a patch, so it's always there if I need it [as long as I have a hex wrench in my saddle bag]. Extra air or a hand pump is good if you don't get all the air into the tube with the CO2, or the tire isn't centered properly or is pinching the tube and you need to let air out.

Always patch the tube when you take it out so if you get another flat, it's already fixed. Also it's best to patch it when you know where the hole is and have checked the tire for glass or a wire poking through.

Remember the stick-on patches don't work very well if they are cold, warm them and the tube up before applying the patch. Glue-on patches are very difficult to apply if it's raining.

Most small pumps don't work very well, you are lucky to get 60 psi out of them. The Micro Rocket will give you 100+ psi but it will take time and patience.

If all else fails, carry a cell phone if you are in an area with coverage, make sure you have the phone numbers of your wife, friends, work numbers, etc.

asiancarbon = sockpuppet for sure, but for whom? madeinitaly?

Well done..

I carry a Innovations SecondWind which has both built into one hand pump/CO2 on my road bike my other bikes have Topeak Road Morph great pumps also.

How does that Second Wind work? I've heard mixed reviews.

The 2nd wind is basically a normal pump that happens to have a co2 option at the end of the pump. Is the hand pump the best on the market, not at all, but it will get you home if you run out of co2.. I have these pumps on all my bikes and have yet to be stranded even when I have run out of co2.. They sell a mini version or full length version, carbon and aluminum options too.. The only downside is that they are presta only, but for most of us that is not a problem.. Most likely the mixed reviews were on the 2nd winds from a few years ago, they did not work so well, the new models have no issues..
