Newb questions about fixing flats.

[hozn]

If you removed the rim strip then it is certainly inevitable that you would flat due to tube being cut by the spoke holes, yeah.

If you did not, then probably just failed to remove the original culprit.

Not sure what you mean, by needing several pumps to install the tube, but you can just blow (i.e. with your mouth) in the tube to give it a little volume/shape initially for install if you are in situation where you only have co2.

Turned out it was a piece of glass that had gone through the tire. Since the tire was balding, I replaced it as well as the tube. The presta tube has been paid forward (Helen said they give stuff like that to bikes for the world) and I also have my old schrader tube at home, that I will attempt to patch SLOWLY and CAREFULLY when I get the chance.

The solution to this, of course, is to just get a frame-mounted mini pump. They weigh and take up about the same amount of room as CO2 and you’re only limited by your arms’ pumping endurance. I went with CO2 when I was noob and just went with what the bike shop gave me, but now I don’t really understand why people waste their time with it. I’m sure many have made some sort of cost/benefit calculation with it…I guess they just view that equation differently than me.

I ride with a pump in jersey pocket (or my backpack) and co2 in saddle bag. I use co2 if I am on a group ride and people are waiting for me to fix my flat. It obviously saves time. Otherwise I just use a pump and save the co2.

Definitely agree that riding with co2 only is foolish. As I think is riding without patches in addition to the spare tube(s).

Also, the variables in our equations probably have different values. 😮

yes, yes, I need to go pick up some barbells or milk jugs or something a bunch of times

In 9th grade we had to give a “demonstration speech”. I chose to give my speech/demonstration on how to fix a flat tire on a bike. It’s a good life skill.

I kind of feel it makes sense to first make sure I really can do a competent patch, before loading up on stuff to carry around to do patches in the field.

The proper approach is to get a flat on a group ride, so everyone can offer a critique of your procedure.

An incompetent patch may still be sufficient to get you home.

Shop for your pump at the LBS and ask to try some out on tires with pressure ratings like the ones you expect to fix. Then you can see if you are strong enough to do it with the selected pump, or need to try a different model. Generally, the skinnier the pump, the less strength you need to get to high pressure, but the more strokes you need to achieve volume. Many manufacturers offer MTB (fatter) and Road (skinnier) versions of pumps. The one I have is on the fat side, but is designed to be braced against the ground like a floor pump so I can put my weight into it to hit 120 psi.

Are you pumping up tubulars?

No, ISO 571 x 23 clinchers.

I ride with a small pocket rocket pump, spare tube and patches. Got burned once riding with CO2 only and had to make the “call of shame”
Very good point on the CO2 for group rides that I had not contemplated and plan to add that to group rides.

So, I finally took some time on Monday to go to the bike room and patch the tire. Checked it this AM, and the tube was still filled with air! Evidently I patched it correctly. So now I will have to go back to contemplating what stuff to carry around.

1 x mini pump/frame pump
1 x NEW innertube
1 x self-adhesive patch kit and tire boot (no cold vulcanizing glue!!)
2 x tire levers
1 x multitool

Don’t skimp. Leave the patched tubes at home or for emergencies only.
