Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

mini pump or CO2?

I've been riding the past year with a mini pump either in my jersey pocket when road riding/training or in my bag when commuting. Good thing I never flatted on the road. The darn thing was busted all along. Tested it last night and it's just broken.

I've never used the CO2 cartridges before. I'm wondering what route to go next. I do not patch tubes, and don't want a frame pump...it's either another good mini pump, or CO2. Your thoughts.

i've never used a mini pump because I've had a CO2 unit since i've been riding. Lots o' flats later, and I couldn't be happier. They fit in my saddlebag well, and will also fit in a jersey if that's your preference. It's quicker and easier. Just my $0.02

Get both in one. Genuine Innovations Second Wind. It's a combo. Not great for handpumping to high pressures, but good for getting the tire started and then pop in an inexpensive, unthreaded 12g CO2 to finish it to a high pressure. If you run out of CO2, you can still hand pump to a ridable pressure.

And fits in a jersey pocket no problem.

I bought a frame pump when I bought my bike and about 8 months later I got my first flat. Replaced the tube tried to pump it up, but the pump was non-functional. Thankfully I wasn't riding alone and was able to get air via another rider's pump. That episode along with the numerous times I've seen someone break their stem trying to pump up their tire with a mini or frame pump has had me looking at CO2 inflators. Curious what other people use.

I think all mini-pumps which can be stuffed in your jersey pocket are junk. They're only good for pumping a little air in the tire before topping it of with CO2.
I now carry a traditional frame pump after flatting multiple times and running out of CO2 cartridges twice last year. I can easily pump 100+ psi. None of my junk drawer full of mini-pumps purchased and tried over the years don't even come close.

If you have reasonably strong arms and a little patience, the Barbieri Carbone mini-pump (weighs 2.5 ounces) can reach 100psi pretty reliably.

+1, I got one not too long ago and tested it before I started riding with it, to make sure it works.

Topeak Road Morph. It's half minipump half frame pump and half floor pump. Therefore according to the math, it's 50% better than everything else out there.

Really, it's just bearly small enough to be considered a minipump, it's got the ease and stroke capactiy of a frame pump, and it's got a hose like a floor pump (so you don't tear out your valve stems).

The amount of CO2 in that bottle is probably about the amount you exhale in ten minutes of riding.

CO2 all the way. Been using it for about 2 years and I have nothing but good things to say about it.

i have had one flat and my CO2 failed me. i had to call the wife and beg her to bring out the floor pump to me as i was about 50 miles from home. i had 3 CO2 cartridges that just burst their bubble when i inserted them. they could have been defective or maybe it was me. anyway, i now have a Topeak Road Morph. later.

I have one that does both.. It is a combo co2 + standard pump.. I bought one to make sure they work and once I got one, bought another for my other bikes.. It is called Dolce Vita, made in Italy and you use it like a regular pump and once you get a little air in the tire and make it is seated properly, you screw in your co2 cartridge and then back off 1/4 turn and you are done.. It only works with threaded co2's. For me having something that works as a pump even I run out of co2 cartridges is great. The only thing I would add is a pump strap to keep it in place.

I've heard alot of great things about the Topeak. That's probably one pump that I would consider.

I use a topeak Micro Rocket Al (65g)
no complaints here, it takes some time to get to ~100 psi, but it'll do that and more.
looks pretty slick too.
the carbon one is 10g less

I can find stuf fon the internet too...

“Rising levels of carbon dioxide in the atmosphere play a big part in global warming,” said lead author Michael Behrenfeld of Oregon State University. “This study shows that as the climate warms, phytoplankton growth rates go down and along with them the amount of carbon dioxide these ocean plants consume. That allows carbon dioxide to accumulate more rapidly in the atmosphere, which would produce more warming.”

I love how these threads devolve into such craziness. If you think 12 or 16g of CO2 from a cartridge is going to upset the ecosystem, then don't use them.

As for me, I'd rather be back on my bike with 2 seconds of CO2 than sit in a ditch hand-pumping a tire.

It's a choice, and I'm sure Al Gore isn't going to single you out if you do or don't make that choice.
