On my way to work today I saw a guy pushing his bike in the Park due to a flat. He was probably 30 mins of walking distance away from home. I helped him fix the the flat but he didn't have anything with him (no tubes, pump, etc.) I ended up giving him my tube and used a CO2 cartridge to help him out. It was a new rider mistake for not being prepared.

My question is: Do you tend to not carry anything if you are just doing a quick lap near your home?

I always have a patch kit and a small tool kit and minor bits and pieces. I rarely carry a new tube unless I am going far away. I quit carrying a complete tire when I retired my last set of sew ups.

i'm i'm just looping around home I figure i can barefoot it back anything under a mile or two.

after a couple of unpleasant walks totaling 3-4 miles, I always have a tube and CO2 with me. But I made the same rookie mistakes.

I occasionally do loops around where I live that don't take me farther than a mile or two from home, when I don't have time to ride any more than that. I still carry all or most of my kit out of habit but when I actually think about it I don't carry anything. Whenever I don't know where I'll end up, or set out to ride farther away, I typically carry a couple tube patches, a tire boot, tire levers, a tube, a couple co2 cylinders and an inflater.

The one time I didn't carry a tube, the flat I got was due to my tube's valve shearing off. I called my wife on my cell and I pushed the bike a mile or maybe two up the road by the time she got to me. Another thing that sucked about that incident was that I was riding on a designated path and at least a dozen other bikers rode by me, none of which asked if I needed anything.

I think a cell phone to call for a pick-up is the best thing to carry, because all else just might fail.

If I'm going to be more than a mile away from home, I carry a spare tube and a pump.

I know the one time I don't is the time I'll get a flat.

When using tubed tires Ill carry a CO2 and a spare tube. When I ride tubeless all I carry is a can of air/sealant. Ill stop and help anyone but if they decided not to carry their own supplies they are not getting mine unless maybe there a total newbie and did not know any better.

That blows. Here I am hoping karma pays off and someone would help me if I need it. But I do carry most stuff that I need barring major mechanical failure. It would have been nice if someone would ask if needed help.

Why would you not carry anything? What's a "quick loop".

Typically, this stuff is carried in a small bag attached to the seat. Why remove this?

Use a simple rule: always carry stuff to fix a flat.

I carry a tube, multi tool, patch kit, CO2, and a fiberfix spoke in a small saddlebag. Stays on my bike at all times (except during a race) so I don't have to transfer from jersey to jersey. All the races I've done prohibit the bag but provide neutral support. Even then if it's a RR I'll stuff a tube, CO2 and lever in a jersey pocket.

I carry stuff all the time, extra weight far out weighs walking anything 1+ miles in clipless shoes. I don't race so there's no need to ever take off the bag or pump.

i normaly ride without. my girlfriend goes to school online and isnt working so shes always on stand by. if she got something to take care of for the day is about the only time i go out with a tube, c02 and multi tool.

I always carry a repair kit, it just pays off to be prepared.

I see a lot of this--I live near the turnaround of a popular loop from Reno into the foothills, so on a summer weekend, dozens of cyclists pass my house. Three or four times a week, I'll see somebody looking puzzled and stupid, or using a cell phone to call for help. Of course I have all my tools, pump etc. right there, and sometimes (especially if it's a hot group of women) I'll go out to see if I can help. Almost always, it's somebody who decided "not to bother" with a repair kit on such a short ride.
But what's the point? A patch kit weighs, what, an ounce, and a pump a pound or less? I keep the stuff in a seat bag and never think of it until I need it, but when I do, I have it. With a little practice you can swap tubes in three minutes, and patch a puncture in four.

always....I keep a mini pump, spare tube, levers in a small ziplock - then just throw it in my jersey pocket, that way no loose items to transfer between jerseys.

Don't leave home without it

That stuff, along with a spare energy bar, is always in my seat bag. Yes, I have a seat bag. And a mirror.

I feel like I'm preparing for a trek in uncharted land, but I hate getting stranded and my supplies still weigh less than the fat I could stand to lose.

When I encounter people walking, I'll offer air and a patch if I'm not in a hurry, but that's it... unless she's hot.

I always carry something. When I sell a first road bike to a customer I try to always explain that it's better to get the necessary supplies and be the person on the side of the road with all the equipment and not know how to change a flat than to have nothing at all and have to take someone else's repair supplies.

I try to keep it to a mile or less without spare tube and pump. I'll occasionally go for a long ride only along bus routes, completely unencumbered.

Once in a blue moon, I'll find myself in a situation. The other day, I'd left my bag o' fixin' stuff at work, but had to go get supplies on my way in. Of course the supply store was about 5 miles out of the way and not on a bus route and of course, I got a flat. I started to continue walking in to work 'til I calculated I was 3.5 miles out! No way I'm pushing flatted bike that far. Luckily I was only 1/2 mile from the bus route, but with a transfer required, it took me 45 minutes to get to work from that point.

I have no one to rely on and live in goat head country. I am also stubborn enough that I detest calling anyone to help me.
Thus, I carry a tube, co2, mini pump, tire irons, and patches.

Spare tube(s), CO2 adaptor and two cartridges, Topeak tool with chain breaker, tire levers, Phone, Zone Bar and money are in my saddle bag whenever I ride more than 3 miles from home. A lot of guys carry a powerlink as well.
I'll stop to help someone who brought there own repair parts but may be stuck but I don't stop if they brought nothing. They can walk.

full patch kit, 2 co2 cartridges, tire lever.

As soon as my flat is fixed I head for home or near transit. I ride in the middle of nowhere. You can't always get the tire to seat perfect or fill it to 8bar. My wife knows my route beforehand and can come get me if something really goes wrong.

all the repair stuff is in my seat bag, where the bike goes: it goes.

Stated cycling last year, when i got a road bike started carrying mini pump, patches, tools, no extra tube. Never got a flat for 2000 miles, got lazy and started leaving the stuff home. Then got a flat about 6 miles from home. Someone stopped, gave me a tube, used a co2 and got me going again. I now carry an extra tube, frame pump, tools and patch kit. I stop to ask if someone needs help if they are stopped on the MUP. Although i dusted off my Bianchi to do about 34 miles and did not carry anything but water and wouldn't you know it picked up a spike that destroyed my back tire and tube. My wife was home that day so called for a pick up, rode to the pickup point with the back tire flat. Now i take all the stuff even for a short trip.
