"The question presented is:

Which do you take with you.

A) Carry Co2 only
B) Carry Pump only
C) Carry Co2 and Pump
D) Make the other cyclists carry them and you say
""Oops, I left my gear on my other bike""
E) Never get a flat cause I ride only on my rims.

And the survey says?

I carry the pump so that I can find the hole in the old tube and seat the new tube and tire on the rim.

Then I use a 16oz cartridge so I do not get tired trying to use the mini pump.

P.S. Did I mention my short valve, long valve dilemna?

The P.S. was for Evan

Check out the thread entitled Purchasing Road Tubes Online.

The P.S. was a joke for Evan

Full-size frame pump that people with minipumps often ask to borrow.

I once had 3 flats on a ride - ran out of patches, ran out of CO2 cartridges, too, had to beg a tube and borrow a pump. After that I retired the inflator.

(This is like Campy vs Shimano, tubies vs clinchers, red states vs blue - nobody's mind ever gets opened by the discussion, let alone changed.)

Tell us about the squeaky shoes, Heath ;^/

Pump only. I have never used CO2. Am I really missing something, or is it just like using an escalator instead of the stairs?

"""escalator instead of the stairs""

Definately a good way to look at it.

I think maybe my bike pump is squeeking, not my shoes, or my chain, or my BB."

The failure rate of people riding escalators seems significantly less than 33%.

I saw a guy in the park last night with two pumps on his frame. A big Topeak with the clip on the top tube and a slightly smaller silver pump mounted on the bottle cage. He was actually pulling over to help someone with a flat.

Not so simple

"B usually. In the summer, no need to hurry, limitless tries for whatever sh*t I might encounter.

C sometimes, for winter and/or off-road rides. CO2 is really handy for inflating the bigger mountain bike tires. Like someone else mentioned ""escalator vs stairs"". Only with the off-road tires, it's like living on the top floor of a 6th floor walk-up! Something you don't feel like doing at the tail end of a 5 hour ride!!!And when the mesquitos is eating me alive, or in freezing drizle, the 30 second it (CO2) save is simply priceless!

E occasionally, when I actually forgot my pump at all! It never happens to the road bike since the pump is mounted on the frame. But the dual suspension mountain bike frame is so strange that a pump just doesn't fit. So when I go for a short ride sans camelpak? The pump got left behind. The mental stress, once I realize I'm riding with no spare, is not fun at all. Abbreviated rides were usually the result."

Usually A

I purchased a Specialized Roubaix Comp this year. It has a compact frame which makes it a chore to remove water bottles from their holders when a frame pump is in place.

I occasionally carry a mini-pump in addition to the CO2.

The CO2 is a backup

Also, CO2 seems to leak out of the tubes after a day, so for me it is completely temporary

yeah, co2 doesn't hold overnight...

...i always end up reinflating the following morning too. small price to pay as long as you get home though.

You forgot option F. I never get flats because I ride only on solid rubber tires. (Though not many people in the club can claim that.)

As for me, it's B.

I've been in many situations where people with CO2 or mini-pumps avail themselves of my at least 8-year-old Zefal frame pump.

Likewise, on both counts.

Pump (only). It's the moral choice.

Only the bicycle industry -- starved as always for novelties to sell us -- could devise a way to make the bicycle a source of greenhouse gas emissions. To say nothing of the CO2 cylinders I see littering the roadside.

I like Zefal HPXs. As do my lightly-laden clubmates, who borrow them regularly.

Belts and suspenders

C. Start with mini pump, top off with CO2. Non-threaded cartridges. Buy them in lots of 15-20 from the gun counters at upstate Wal-Marts. Share liberally with downed fellow riders, gets us all back on road faster.

Good timing

"Earlier today i got a flat and had with me a spare tube and a couple CO2 cartridges. Granted it was my fault for mistakenly buying a short stem tube at some point (and deciding to just replace the tube instead of patching the old one), but nevertheless I was stuck fumbling. Because of that short stem, the CO2 tip wouldn't fit so well and I wasted the cartridges without fully getting the tire inflated. It did give me enough air to make it to a shop, where I used a real pump.

I've had success with the CO2 before, but I realized today that without a pump, you really have a limited amount of tries to get it right, and then you're out of luck. Not to mention anything else that might come up the rest of the ride.

I have a related question.. the culprit for the flat was a piece of glass - maybe 1/8 - 1/4"" round. The rip in the tire isn't visible unless I really pull at it, and only then it's barely visible. Do you think I need to replace the tire or patch it some other way? Or should it be ok as is?"
