Any specific one(s) that are commonly used? I've had a hard time finding a pump that didn't bug the crap out of me in my rear pocket, and I dislike the clips that attach to the frame. I'm seriously looking for a good product recommendation/endorsement!

Oh, welcome back, btw.

I always wanted to try this with bike tires.
I think I'd need UST, however.

Blackburn, Zefal, Park Adjustable. I ride a 56, so it fits nicely under the top tub with no clips.

Plenty of existing threads about frame pumps.

once you go lezyne, you never go back.

I don't get enough flats to be fast at it at all.

Here's a youtube video where the rear tube change takes 1:37. It looks faster to do both the tube and the bead at the same time. But he doesn't really check carefully for glass stuck in the tire. I would find the hole in the tube and try to match it up with the tire first.

Blackburn SL Airstik. Small enough to stick in a small seat bag. It actually works. Takes a bit of time. So I carry one C02, and the airstik as a backup.

Lots of people like Lezyne pumps, however, IIRC they're just a bit longer, and harder to fit in a seat bag.

Yeah, otherwise you might need another 1:37 when the glass pops the second tube.

I have a Sunlite minipump. I used it once in the field and it was terrible. That's when cartridges started to look attractive. The other thing is that I have 5 bikes I ride with regularity; the minipump I have installs with a bracket on water bottle cage braze-ons, and it's a pain to move it from one bike to another. Stuffing cartridges into a saddle bag is a lot easier for me (espeically since I keep a kit of a couple cartridges, a couple tire levers, and the nozzle in a ziploc bag). Also, I have Schwalbe Marathons on the bikes I ride most so flatting due to glass, etc., is greatly reduced.

If that impressed you then the Pcad routine sub 3 minute tire change would rock your Left Coast World.

Minipump->pocket.

PSIMET is mad fast at changing flats. typically when on a ride with him and a flat takes place he watches for 30 seconds before deciding the "flat" rider is taking way too long and he takes over. a few minutes later we are back on the road. later.

That assumes, of course, that one wears a cycling jersey. I prefer cotton and rarely wear a jersey with the pockets on the back.

Well you only got yourself to blame for that one.

Hopefully you don't get more flats in a given ride than C02s in your pack. Aren't you a long distance rider/tourer???


FWIW, I carry 2 c02s and a pump on every ride. The pump is just to give the tube a lil air before I install it and in case I get more flats than C02s a I have.

No, I don't ride distance too much. My commute is 34 miles round trip, I usually ride something like that, maybe a little more, on Saturdays if I ride my club's breakfast ride. Almost all my riding is in and around Fort Worth and most rides start from my house, so in a worst case situation I can get a ride home from a family member. The worst problem I've had so far was a mishap that made my bike unrideable (not tire related) at the beginning of a charity ride. I walked the bike home 4 miles.

I usually carry one tube and two cartridges.

Also I think I said upthread that most of my riding is on Schwalbe Marathons which are supposed to be flatless (althought nothing is 100%).

Had my worst flat *ever* yesterday on a rental bike (Las Vegas):

- put the spare tube in the tire, it wouldn't inflate. I thought the problem was a bad valve, so I went back to the original tube.
- patched the original tube - patch didn't hold (I was in a hurry)
- patch #2 - success! mounted the wheel, but tire was losing air even before I took off. pulled the tube again, and found a 2nd hole
- patch #3 - success. mounted the wheel for the 3rd time, and took off.

This was not a 4-minute job.

I went back to my Zefal.

That's fast but I am more interested in his average time for changing a tire.

Full sized frame pump. I switched from cartridges a long time ago. Not much more effort and it doesn't need to be replaced after every use.

Changing a tire doesn't take that long. It's carefully inspecting the tire casing for the culprit that takes a couple of minutes. And that is rather important.

If you've got some kind of rag, you can run it along the inside of the tire. If it's some kind of sharp debris, it will usually snag on the rag.

ONe time i lined up at the start line to a race, the announcer said 5 minutes to start, i looked down and felt/ saw a flat rear tire. I started said race on time ish, about ten seconds late. thats with going back to a friends car, trying to find the keys and then reaching through the window to get em. Thats not to say i finished more than a mile of the race before my second flat... but, the first change was an impressive one nonetheless. Probably about 3.5 minutes of actual changing/co2ing and wheel replacing. and it was on a steel bike with semi horizontal, narrow dropouts, which require aot of extra attention for putting the wheel back on.

Half the time it's a piece of glass or wire recessed in the tire casing that won't make itself known until there's 100lbs of air in the tire, then it's kaboom all over again.

two minutes if I don't have to find the cause.

Keep in mind that 4 minutes was the total non-moving time on my Garmin and he wasn't being partcularly rushed. It's not like it was a speed flat changing contest. And he did check the tire.

I'm amazed that people think that 4 minutes total is a blazing fast time to change a tube (including checking for whatever punctured). If it takes me more than 4-5 minutes, I know I've been REALLY flailing

Did you do the nice teammate thing and roll up his punctured tube for him while he was pumping up the new one?

4 minutes is pretty fast with a mini pump instead of co2. I didn't roll up the tube though, I was having a conversation with the other guy

Besides, the part that impressed me was that he had the tube out and ready before he even stopped.

See if you can guess who it was.
