Impressive Flat Change
 

I wish I got some video of it, but I didn't. Ex-pro teammate looks over and asks "does my tire look low?". "Um, yeah dude, it's kinda squishy".

Before he is even stopped he has whipped out a tube, and less than 4 minutes later he has reinflated with a mini pump and we are rolling again.

I was seriously impressed, and I don't impress easily.

I can change one while doing a wheelie.

fast

I can do it all in under three minutes if it's the front and I don't mess up (with CO2).

Impressive.

After being banned for two weeks UMD comes back with a "wow that's a fast flat change"? I guess it'll take him a while to build up momentum again.

Getting the tube out of your seat pack before you stop would be pretty good though.

sometimes i like a fellow biker's flat repair to take a little longer while i rest:D

I changed a flat on a single speed with bolt-on wheels & rear facing dropouts in 10 minutes. I was trying to make it to a group ride.

I can do it in under 40 minutes if the planets are aligned properly.

It was the rear and no co2.

Pockets, not saddle bag...

I helped someone out today who had a problem with his replacement tube. The valve stem on his spare tube was short, and it barely stuck out of the rim. (I don't know why his spare tube had a 36mm valve stem [I have never seen shorter but it may have even been shorter than that] while the ones in the wheels were 60mm??) I wonder how long he was waiting on the side of the road. Unfortunately I didn't have my Lezyne hand pump which would have been able to grab on to the end of the valve stem, but we managed to pump his tube up enough to get moving again and didn't have to resort to patching the old one which would have taken a while.

The fastest I've ever seen in person (rear wheel, mini pump) was in the range of 5 or so minutes.

I was at the back end of a group ride during the warm up when this guy's tire blew. So, I figured I'd wait up for him while he fixed it. However, I'm pretty sure his tire originally blew because the tube was improperly installed to begin with, so that made me less impressed with his speed.

Of course after this fix we were way behind the group and this putz tried to make up ground by hammering 25mph down a bike path to a meet up spot. I let him go on his merry way at that point...

And even if we didn't wait for him, he could have caught us, especially since he did at least 2/3 of the work between the 3 of us.

Me, too, but I can't ride the bike--a CO2 cart won't pump my 37mm Paselas up hard enough. With a good frame-fit pump I can do four, at least one of them spent pumping. Generally, though, I like to sit on the curb drinking water for awhile...

Interesting that all you roadies are using minipumps. I switched over to cartridges a while ago. A lot less effort.

forget the tire change, the reinflation with a mini pump, now that is impressive ;)

Pumps have an infinite amount of air, are lighter, and cheaper.

Agreed. I'm so clumsy that I always worry about f'ng my CO2 cartridge. I'd rather just have the security of a pump.

And it was nice that you waited for him...no need to make him chase you needlessly...

I think he decided to make up the time anyway. He really hammered for the next half hour or so and we just sat on his wheel. :lol:

Full size pump under the top tube for me.

Are they lighter? They're only cheaper if you get a lot of flats.

They are lighter than carrying two carts. They are cheaper over time. I think it's actually more likely that a stereotypical "roadie" would use co2, but it seems that that more experienced cyclists cary pumps. All the pros and ex-pros that I know carry pumps on training rides.

The weight difference is pretty negligible. Plus, I'll sacrifice a few grams if it means not being stuck somewhere with no way inflate my flat tire.

Even if you don't get a lot of flats it's cheaper. 5 or 6 CO2 cartridges a year can add up. Especially considering you pay once for a pump and get unlimited uses. Providing it doesn't break...

It takes me about two days for the front and 10 for the rear.

I carry a minipump but it takes forever to use, so I also carry a CO2 cart for when I'm lazy

I also find it very difficult to get a tire over 80 PSI with a minipump.
