Pump vs CO2 weight(11 posts)

Pump vs CO2 weightMGS
Jun 9, 2003 4:36 PM
I recently weighed my two large C02 cartridges, inflator head and Crank Brothers mini-pump. The weight was 255 grams. This is what I consider necessary to be prepared for two flats and a pump to start or find a hole in the inner tube.

The weight of the Topeak Road Morph, which is great for inflating tires up to 110lbs without a sweat is 255 grams.

Why am I carrying around the CO2, and running the risk of not being able to repair a flat if I ruin a cartridge?

Why aren't we all just carrying a good mini or standard pump?

And it will pump you up dependably for years. Sounds like you've made the case, but don't try to convice the dedicated CO2 users - pumping is such hard work (whine!).

I got a Zefal HPX pump to put on my long-distance bike. Out of curiosity, I weighed it and my CO2 inflator with 3 cartridges, which is what I usually carry. The weight was nearly identical, with the Zefal perhaps slightly lighter. I figure you need at least 3 cartridges to be safe in case you flat 2X or more. Carrying the frame pump also freed up some extra space in my seat bag. I just wish most bike manufacturers hadn't quit putting pump pegs on their frames -- the ultimate in weight weenie-ism.

bravo! plus the frame pumps look ugly

Riding home from work today I came across a woman walking her bike. I stopped and asked if she had a flat tire. Turns out she had changed her tire but then screwed up putting in the C02 and had been walking for 2-3 miles with other cyclists passing her without stopping to help her before I came by. I pumped up her tire with my frame pump while she explained that she didn't carry a pump for weight reasons but was no going to start carrying one...

I think if one is smarter than the inflator, then blowing the CO2 is not a problem. I'm not terribly bright, but I haven't done it yet.

However, to be sure I use the inflator/pump combo.

the plastic mount for my frame pump vibrated scratches all into the paint and the straps looked like an eye-sore, but that's just one reason I went to CO2. For real though, I nice full size frame pump on the right mount is hard to beat for versitility for general rides, no arguing.
And your arms look great after pumping a tire. nmdzrider

Aerodynamics. When you want that slight edge, carry the CO2, when you need reliability, go with a pump & a tiny shraeder valve adaptor so you can fill it "5 seconds" at a gas station air compressor after getting it up to minimal pressure to reach the nearest filling station.
