Had my first flat...(18 posts)

Had my first flat...dgangi
Nov 24, 2003 5:19 PM
I am relatively new to road biking - about 2 months and counting. In that time I have put over 600 miles on my bike and have been fortunate not to have any flats in all of those miles. But, as luck would have it, I had my first tire on a 50-miler this past Saturday.

Anyway, when I bought the road bike I decided to try CO2 instead of a dreaded pump. So this was my first chance to use CO2 (use a pump on my MTB) and boy was I impressed!! Unlike my MTB where it takes me 100 pumps and 5 minutes to get my tires inflated, the CO2 blew up the tire in 1/2 second to 100+ PSI.

One thing I will say - the tires are DAMN hard to remove and replace. My MTB tires nearly come apart in my bare hands without tools. But I really had to force the 700x23c tire (Vittoria) off and on the rim. Good thing my tire levers worked well.

Anyway - moral of the story is that my $12 investment in the CO2 was *well* worth it. Now I won't complain about having to spend $2 on each cartridge. In fact, I can't see why anybody would carry a pump anymore, especially since it is so difficult to use those little pumps to inflate 100+ PSI into a tire.

Too expensive ...PaulNYC

Go to Target and buy a whole box of CO2 for BB guns. It's a lot cheaper!

Good luck.

I did carry CO2 for a year or so and found that I would normally take 3 cartridges and the inflator. This is OK for most circumstances if the cartridge works first time and the full cylinder goes into the tube and not all over the rim. However I have now gone back to a pump which will give me (and anyone else) endless re-fills in under 100 strokes to 90psi. The pump weighs 145grams, less than the CO2 set up, and takes up less room in my pockets. For racing, I would probably use CO2, which could save 2-3minutes.

Innovations Second Wind- CO2 and pump in one. Absolutely awesome. But since I've been using Slime tire liners I haven't had a flat in over a year and 5,000+ miles which is even better!

I still swear by the frame pump if you have room and don't mind it. Takes a lot less than 100 strokes to pump 100+ lbs. and so much easier than the compact pumps, which never quite get enough air in the tire.

My frame is too small to fit a frame pump without affecting the water bottle that is mounted on the seat tube. So my only options were a mini pump or CO2. And since I loathe the use of mini pumps for high pressure situations, I decided to go with the CO2 option. So far I think I made the right decision. I can't imagine cramming 110PSI into my tire with a 6" mini pump!

The only issue I found with my decision is that I bought the *really* compact CO2 system, which uses the screw-on cartridges. This was the right decision from a weight and size perspective (have a small seat bag that it must fit in), but it was the wrong decision from a long term cost perspective. It turns out that the threadless CO2 cartridges cost about half of the threaded ones since the threadless are on sale at Walmart and the threaded are only available at the bike store.

Try putting it along your seat stay.
..why anybody would carry a pump anymore??Alexx

Well, you;ll find out the first time you run out of CO2, either from having too many punctures (a thorn patch will do this to you..), or if you find that your spare cartrige is dead. Then, you'll be 3 miles from the nearest phone (probably an area without cell coverage, too), wishing that you still had a @^#$ing frame pump!

(Note:should this happen to you, remove the cleats from your shoe-3 miles clopping down a paved road will ruin them. Don't ask me how I know this).
It is not important for me to carry a pumpbigrider

I carry CO2 with three cartridges, spare tube, and tire patch kit. It is important that one of my riding buddies has one. Ha Ha.

I know this doesn't help when you ride solo, but when riding road I have found the above setup to keep you riding 99 percent of the time you get a flat.

If I am in the woods there is no way I am not having a pump. Just too many variables and you would have to carry a dozen of the small cartridges to get that 99 percent comfort level.

By the way, I am shocked no one mentioned the dog stick factor for having a frame pump. You can reach out and touch rover with a good metal frame pump.

does not have the same impact as a pump.

Question... Do you take the tire completely off the rim? If so, don't! Just remove one bead and pull out the innter tube. It will be a lot easier! Also, once you get the technique right where you put the one side of the wheel on your stomach and use your palms to roll the last few inches back on I think you will find it not to be too difficult, unless you have some atypical tires.

I do not remove the entire tire from the rim. I only remove the one side.

Just getting the process started was a real PITA. My MTB rim/tire combo is loose enough that I can take the tire off with very little effort. In fact, I got my MTB tire-changing routine down to just a few minutes as it is important in a race to have a fast tire change.

My current road rim/tire combination is obviously a little more stubborn.

Depends on the tire/rim combo...peter1

I have Velocity deep rims and find that tires come off easily with my hands. But oddly, my mtb rims (mavic 517) seem to have a vise grip on the tire beadss. I don't flat often on the road, so I just carry a minipump. Usually I can get about 85 psi in, enough to get home.

I have the opposite experience. My MTB rims are Mavic 517's and my tires come off and go back on very easily (tires are Bontrager Jones). My road wheels are Ritchey Aero Pro's and the tires are Vittoria kevlar something-or-others and the Ritchey's seem to have a vice grip on the tire. It was a real PITA starting the removal process and even more of a PITA getting the last bit of the tire back on.

Oh well. At least I know what to expect next time.
