Co2 or hand pump

Looking into doing smaller tours to start (3 - 7 days or so). Carry Co2 for my day rides now. Do you touring folks carry Co2 or a hand pump with you & if so what brands? When you are farther out, it seems to make sense to carry a hand pump but just wondering.

CO2 can run out... handpumps last as long as you need them. I always carry a frame pump on my bikes. You never know when you might need it. It takes a little time to pump up the tire, but I know I can keep riding.

It gets rather expensive to do regular inflations with carts. I use a hand pump when you're inflating 12-20 times over a month's tour. For the weight difference on tour, I see little difference, probably less than 2% total load by my calculation. I carry a Topeak Road Morph.

The most popular touring pumps appear to be the Topeak Road Morph G and the Lezyne Micro Floor Drive. I own both and each have advantages and disadvantages so I am not going to say which is better.

CO2 is for quick fixes when you may not have time to pump the tire up. However CO2 will diffuse out of the tube rapidly...usually overnight...so you shouldn't depend on it for long term.

While you'll have some diffusion with high pressure air, it won't be all that rapid. I usually go 2 to 5 days without pumping up tires.

Heh. When I started using CO2 for road flats I didn't know that. The first couple of times I used it I thought I had gotten slow leaks when I found my tires were soft the next morning. Checked the tubes and found nothing. Inflated with the floor pump and everything was fine. I finally got an inkling and asked a friend about it.

I carry both CO2 and a hand pump. CO2 if a quick repair is needed and in combination with the pump for large volume tires. 16g for smaller tires and 25g or a couple 12gs for larger tires. Nonthreaded cartriges are a little cheaper. Just have to make sure compatible inflator and cartridges are packed.

I don't tour, but FWIW I had the internal CO2 debate a while back, and came out firmly on the pump side for any situation I'mm likely to find myself in. I used to use a Road Morph G as my primary carry pump, till I switched to the Lezyne Pressure Drive to have something even smaller for local rides. But if I was touring, I wouldn't hesitate to bring the Road Morph as my only inflation method. Completely dependable and strong. I can take a tire from 0psi to slightyly over 100psi in less than 2minutes. What more can you ask? My only fault with it is that the presta connector is not screw-on. Otherwise perfect IMO.

Hand pumps have been known to fail, so it can't hurt to carry both.

buy a pump that uses both like the GI secondwind.. It come in std size and mini versions and alloy or carbon option.. I just use the alloy minis on most of my bikes.. It is a std pump that has a threaded co2 option and they work great in both regards.. If you run out of co2 cartridges you can still use the pump to get your tires to pressure.

My touring bike has as long a frame fit pump as will fit on it.

There is no denying that the Zefal pumps are rugged but the Topeak is just a better design. I've used, and admired, the Zefals d up until 2000 when I got my first Topeak Morph. After using it once, I knew I'd never go back to the Zefal.

Thanks for the replies. I will start looking into a small pump (morph). I tend to inflate every ride with my normal bike pump I keep in the car for the day rides. Most likely will do the same daily before heading out after an overnight so makes most sense to top off with a little hand held. Thanks again and as always, enjoy the ride!

Over-kill. If you are really worried, carry two hand pumps. I've seen people screw-up C02. I've never seen a hand-pump fail.

If you use CO2 on a tour, you are left with the problem of recycling the empties and spending time replacing them. Why?

This. If I was really paranoid, I would carry my Road Morph on the frame, and my Lezyne Pressure Drive (size small) in the under-seat bag. The pressure drive takes up less space than a granola bar.

The seals can go bad and they can get dented. Just because it's never happened to you is irrelevant. I'd rather have a backup than walking several miles.

I have seen a hand-pump fail but that was because it was a crappy design. And, I hate to say this Booger1, it was a Zefal. A Zefal Double Shot, to be exact. If you want it, I can give you directions to where I threw it about 15 years ago. But that's the only one that has ever failed me.

I have used a Wrench Force frame pump for the last 5 years; since I forgot my Zefal when setting off on a tour. I still use the Zefal.

We were 120 miles into our across the U.S ride when we stopped at a bike shop for an incidental item. When we leaned the bikes against the bike rack, my wife asked, "where is your pump?". Oh @#%*! I went in and bought a frame pump that would fit under the top tube. It was good timing on her part, because the next bike shop was down the road a ways. I'm still using that pump with no problems. I'd have also worried myself over those first 120 miles, if I would have realized we were without a pump. I now believe in checklists!

My wife carries CO2 in her seat bag for Triathlons, but for every day use they are a pain for all the reasons mentioned above. The CO2 inflation kit stays at home for everyday riding.

I hate seeing the used cartridges on the side of the road, sometimes with an abandoned tube.

I've had this Bontranger Morph-like mini pump for years and used it a lot, and it's still going strong: http://bontrager.com/model/08340
