5 flats in two weeks(11 posts)

5 flats in two weeksbear
Jul 10, 2002 4:34 PM
I am riding longer and father so with that I am getting a flat like almost everytime I ride! my tires continental 3000 have 1800 miles on them. every time is cost me $6 dollars for a tube ( carry two just in case) I wonder if it would be ok to use the glueless pathes to repair the tubes, $ 6 a pop is not funny! I am also consideraing the gator tires from continental! they weight a little more but maybe they cut down on flats though? thanks lots for any coments!

it sounds like you need to change your tires - 1800 miles is a fair amount of mileage for road tires. i haven't ridden on conti 3000s so i can't say for sure if they've reached their limit. i think a good indicator is multiple flats in a short period of time.

$6 a tube is rather expensive for a tube - either get patches or order from pricepoint.com (10 for $20).
Some thoughtsKerry

First, why aren't you patching your tubes? You can easily patch them with a normal patch kit for about 50 cents per patch, tops. While some like to ride only on new tubes, many of us think nothing of patching a tube 5 or more times. Don't use the gluless patches except in emergencies (like you get a second flat on a ride) because they typically don't last a long time. Have you diagnosed your flat pattern? Do you get punctures at the same place? There may be a glass shard, thorn, piece of wire, or casing abrasion in your tire that is puncturing the tube at the same point over and over again. The first thing you should do when you get a flat is inspect the inside tire casing and be sure that there is not something imbedded in the tire. Some say that they get more flats as a tire wears out, though this has not been my experience or the experience of those in our ride group. The tire that consistently gets mentioned as having high flat resistance is the Specialized Armadillo, but no one claims that this tire has a good ride, especially compared to the GP3000.

check your rim tape and rim surface and the inside of your tire for any potential sharp spots...

sometimes crap rimtape causes flats...

Lots of new road bikes come with plastic rim strips that migrate over to one side and expose one of the spoke holes. The tiniest bit of spoke hole showing will cause your tube to cut.

Five flats in two weeks is unusual. I'd suspect you have an unresolved problem that is causing them. You will continue to get frequent flats until you figure it out.

I did about 800 miles ago and haven't flatted yet.

Best of luck,

I have a pair of Conti Ultra 2000s with over 1600 mi on them. Naturally the rear has developed a worn area and I had one flat due to a staple. (which I patched with a glueless) So my 2-cents is that I always deflate after I ride, wipe them off and check for imbedded stuff. I then have to inflate before I ride but it is a chance for me to look at the condition of the rubber again and ensure correct pressure.
I have booted the front with a Tyvek strip at a suspicious sidewall point. On top of that the front still has remnents of the tire mold flashing visible at the center, so I hope to get loads more miles out of it, knock on my wooden head.

The glueless patch can hold very well if applied correctly and you are always checking your tire pressure...
Conti 2000s - grip?PdxMark

How well are those gripping for you? I have them on a commuter and they seem to have noticably less grip than Axial Pros and even Gommitalia Calypsos that I'm trying on another bike.

I've noticed the lesser grip in climbing, regular accelerations, and cornering. In the cornering lesson I had a bit too much speed on a descent. I started to slide each time I touched my brakes, so off the road I went. Thankfully there was a nice berm built-up at the corner to ride up and stop me. It would have been a long fall without that berm.

So far so good. But then I live and ride in San Diego, CA. We have a drought here so I haven't seen rain or even a moist road in some time. My biggest gripe is the "threadding" the sidewalls exhibit as well as the "suspicious" scrapes I noted also on the sidewalls.

The threadding I hear is common to contis but disconcerting nontheless. I picked them at the time for their sale price and had a fairly good experience with Ultra 3000s.

Read Kerry's post very carefully. Analyze each flat until you know exactly what caused it, and then don't do that. Of course we all have some flats but you're have way too many. Find out why. And you got some good advice from the others too. Poor rim strips are often the cause of frequent or "mystery" flats. I've also experienced several flats due to defective tubes in various brands.
Another good thing to do is index the tire on the rim using the valve stem hole and the tire's label. That way you can compare the position of the hole in the tube with the tire and rim. Flats are no fun, I average 1 per 1000 miles.

i figure it's time for a new tire as the old one is thin enough to puncture all the time.
