It had potential, then.....phisssss* ?'s about CO2Kristin
May 16, 2001 7:20 AM
And it took 2 experienced riders to get the tire off. We immediately discovered a whole in the second tube. It took about 40 minutes to get going again--losing precious light along the way. I went home, patched holes and changed the tube again for practice. It took me 25 mintues to get the tire off and another 15 to get it back on. I'm wondering if my Michellin Alial Sports will loosen up over time and changing, or will they always fit that tightly? Should I invest in a different tire? The CO2 can I had also doesn't work very well...Its a German brand called "Airchamp". Three people tried and couldn't tap into the cartidge, so I'm gonna return it. What should I get instead--what brand pumps work well??

works great for me. It accepts both threaded and unthreaded catridges so you can use the cheap catridges available in Walmart made for air-guns. What kind of tire lever do you use? That may have a lot to do with how efficiently you can get your tire off and on. Technique matters too. AlthoughI use Park tools tire levers I prefer the one made by the Crank Brothers (?). I have used them once and they work great.

Some tires are flexible and some are stubborn. That's how life is. Anyways, welcome back and I hope you will not be flamed.

i have one of those threadless "inflators" or something like that...its yellow at the bottom and a black trigger...($18)
i went to walmart, to the guns & Militia section and picked up a box of 25 CO2 cartriges--cheap and they work great....
i carry one in the inflator and one extra...

my axial pros have loosend up and are easy to work with now...
are the sports a wire bead?? i put some cheap slicks with a wire bead on my old mnt bike for my dad to use and i spent an entire saturday trying to get those things on!!! (well maybe not the ENTIRE day..but still...) plus i got my thumb pinched between the rim and the wire beed and made a huge blister...hurt like a bastard....

One of the reasons I now use Vittoria tires. I could never get the Michelins off/on my rim without using a lever...which led to pinched tubes. Michelins and Conti's seem to fit very tightly on a rim. Just my $.02

It's amazing how we all can have different experiences with the same stuff. Contrary to your experience, I have a set of Acial Pros that are a breeze to get on and off (and they've held up wonderfully through the many corners of several crits). Recently, I bought a pair of Vittoria Ultra Speed tires (700x23 kevlar-beaded clinchers) and found them to be uber-tight ... so much so that I had to leave them on the wheel for a week (when I wasn't riding) without an innertube just to stretch the tire enough so that I could eventually get it on with an innertube (this occurred last night, hallelujah!).

my 2 cents
Vittorias are suppleMeDotOrg

Of Michelin, Continental and Vittoria, Vittoria are by far the easiest to get off the rim. I can mount a Vittoria without tire irons, and I don't have very strong hands.
the two easiest tires to get on and off...keith m.

the vittorias and performance brand forte' kevlars. the performance brand are on sale right now ($14.99) and are only 215grams, I highly recomend them.
Tight tiresDCP

Tightly fitting tires are a good thing. They are less likely to come off the rim while you are trying to stop when they flat. Work with them and you will get the hang of it.

If you are willing to trade performance for greater puncture resistance, consider a kevlar reinforced (not just the tire bead) tire like Michelin's Axial Sport.
Toss all that CO2 junk and get a Zefal HPXCory
May 16, 2001 9:58 AM
It's probably my old-school upbringing, but I've given up on CO2 inflators AND glueless patches. Give me a Rema patch kit and a Zefal HPX and I'll ride around the world!
Yup - that is the answer for sure (nm)Pumper-man

I have problems w/ this pump. It works fine to get you home, but pumping a tire up to 110psi? It takes forever and you'll have an aneurysm long before you have the tire fully inflated. If your experience has been different I'd like to hear about it.
Works for meBrian C.

Happily, it has been needed just once on the road, and it worked fine. Yes, a little effort was required to get 100+ psi, but at least it made it to that level. With a previous cheap pump, I was lucky to get 65 psi. As with many other aspects of cycling, you get what you pay for, I guess.
Sorry your experience wasn't satisfactory.
But it's good to have varied opinion to help people make their decision.

Pros and cons...vram
May 16, 2001 2:37 PM
Zefal HPX
Pros-Air is free, never run out of air, inflates upto 110 psi, can be brandished as a weapon (against animal and man).

Cons-Have to huff &puff to get tires inflated, since it doesn't have gauge must rely on guesswork, most new bike frames don't have pump pegs, mars paint-finish on bike, takes time to inflate tire, need to remember to carry it, unwieldy for races.

CO2 inflator
Pros- Easy to carry, inflates fast, no need to carry gauge-capacity of catridge will determine tire pressure.

Cons-expensive (less so if you buy unthreaded from walmart), if you have more flats than catridges you are in trouble, CO2 will escape from tube within 24 hours.

I always have 3 catridges with inflator in my saddle bag. And carry a mini-pump in my jersey pocket. Never had any trouble with flats. In the rare instance I have more than three flats on a ride, I have my minipump to get me home or to a gas station. Tip: Always carry a schraeder convertor (?) so you can air up at gas stations.

Have the lbs show you how to use the speed lever. Then go have a flat so you can show everyone how quick you are up and pedaling. ;-)

After many years of using a trusty Zefal frame pump, I took the plunge last year and bought a Innovations CO2 unit(like one other poster, I use the one that is yellow and black-Ultraflate?). Anyway, couldn't be happier. As for tires, I am using Performance tires and have notice that they are easier to put on than the Michelins. Other than that tire changing just takes practice to get better.
Sometimes cycling is hard,STEELYeyed
May 16, 2001 11:08 AM
but if it were easy everyone would do it,I do some rides with a lady that has been cycling for 20years,she is no stranger to flats,and to this day she still cannot repair a flat,she slimes her tubes and runs Armidillo Turbos, even though the wieght is high,she just can't take a chance on a flat when she is alone. Speaking of flats....I flatted night before last,10miles from home, 90 degrees+,I open my seat bag,and discover a vast emptyness,it seems as though my son "borrowed"my flat repair stuff,because someone"borrowed"his and never replaced it,thank god for cell phones,it saved me a long, hot walk home.
it could be the rimmm

I've got a set of old Ambrosio rims that seem to give a tight fit regardless of the brand of tires. I've even broken tire levers trying to dismount a tire from them.
Best pump/CO2 on the market. . .Erik W

At least in my oppinion is the Innovations Second Wind IH. This is a mini pump AND a CO2 pump. It has a universal head for either schrader or presta valves. It takes threaded 16 gram cartridges or the less expensive unthreaded 12 gram. I'm basically cheap so the way I do things is when I get a flat I use the mini pump to easily inflate the tire to 30 psi then use a whole 12 gram CO2 cartridge to bring the tire up to between 110 and 120 psi. It works great, is quick and is inexpensive. You can get one of these at

You can buy refill cartridges in bulk for less then a buck a piece. I like it because I have the back up of the pump if I ever screw up using the CO2, admittedly though it would be difficult to fill the tire up to the proper psi with just the pump alone. It's compact and easily fits in a jersey pocket.

I use the Innovations Second Wind CO2 pump only because my OCLV frame doesn't accept a good "stick" pump very well. The CO2 pump works well for emergency road use; however, I notice the CO2 seems to leak out of the tires ( over time ) faster than plain old "air".
For tire removal and installation, you just can't beat the Crank Brothers Speed lever ( ~ $8.00 ) -- since buying one of these at the LA bike show 3-4 years ago, I haven't needed tire levers at all.
