To patch or not to patch, that is the question?

Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

To patch or not to patch, that is the question?

I've heard both ways, so thought I'd see if there is a consensus of opinion, and figured maybe it depends on the tire and tube.

Running 700 X 25C tires with min tire pressure at 100 PSI and max at 130 PSI, and run them at about 110 PSI.

I've heard once a tube has a hole, except to patch it to get back home, don't patch it, throw it away. I've also read about not being a Tube Snob, and to patch a use them.

Just wondering if I should patch a skinny tube that runs high pressure or not? I can see it on a cruiser or maybe a MTB tire that's running 40-60 PSI, but not sure about 100+ PSI.

All help appreciated.

Thanks in advance folks.

I personally don't patch just because I'd be thinking about losing a front tire the next time I descend. For the sake of a fiver, I'd rather not think those thoughts.

This is a no-brainer. Who would waste time patching a $5 tube and then taking some extra risk of another flat. I suppose only the people that enjoy sitting in a ditch repairing flats.

I've been riding on a patched tube for months. No problems whatsoever.

Glued patches are meant to be a permanent fix (if you do it right). Glueless patches are temporary just-get-me-home fixes.

If you wear a top hat when you're not wearing a bike helmet, patching is not an option.

I say patch away. I've got numerous patched tires running 110PSI right now and have never had an issue with them (I do use glued/permanent patches).

I never beat my work-mate's record of 20 patches on one tube, but it goes to show a properly glued patch is permanent, not to mention costs 25c as opposed to $4 and is way less wasteful.

For the sake of the two-three tubes I have gone through in the last year, I just use a new tube.

I patch all my tubes. There are plenty of tubes I'm riding right now that have patches, sometimes multiple. If you do it right, with sand paper, rubber cement, and a proper patch, they're perfectly safe.

On a ride, I carry a spare tube (don't we all?). If I flat, I'll replace the flat tube with a new one and then throw out the one that flatted. Only if I flat again on the same ride will I patch one of the tubes (the one put on after the first flat) and then not give it a second thought but still replace the damaged one in my seat bag with a new one. I'll ride with the patched one until the next time I'm doing maintenance and then replace with a new one. Luckily I've not flatted a front tire on my road bike, otherwise I might be more cautious.

I'll sometimes patch a tube on a long ride instead of replacing it, just to take a break.

A patch properly done will not go flat. I always carry a spare tube and the spare tube is almost always patched. I dont see whats so difficult about patching tube when you get home from your ride, takes 2 minutes and you save yourself 5 bucks each time...

Anybody whose answer is based on the safety of a patched tube - your answer is based on a faulty premise, that patched tubes are somehow prone to failure. They are not.

Why patch a tube when another tube is $5? Because another tube is $5!

And in NYC, they're actually $7, when really they should be 3 for $10.

If I bought a new tube every time I flatted my annual tube budget would probably be somewhere around $200.

That crap adds up!

Why buy another tube for $5 when you can just patch it?

+1

Currently all my tubes have patches, my record so far is 10 patches on 1 tube. None of my patches have failed.

You guys must light your cigars with hundred dollar bills.

I'll put in a new tube on the road (for the first flat -- patch kit for the occasional 2d or even 3d flat) and patch at home at my leisure. If you take your time and do it properly, the patch is as strong as the rest of the tube.

Less than 30 miles from home, I just carry a patch kit.
More than 30 miles from home, I carry an extra tube in my back pocket.

I don't patch on the road, but my spare tube and tires have patches w/o any issues. For me it's more of a 'waste not, want not' kinda thing.

I buy cheap tubes and toss em when they are punctured. Who knows what other fatigue/valve issues they might have on them, let alone holding 120 psi on a patch.

I've ridden patched tubes with no issues, and patched tubes all the time when I used to mountain bike, but I flat so rarely on the road that I dont care to keep the tube.

patch. I ride on 120 psi for my 700x23 and my last tube on the rear had 4 patches before the valve stem broke(not because of the pump). The roads out here suck and I saved myself from using up all my spares.

I can never get the stupid patches to stick, so I don't bother. I go through, maybe 4 tubes a year. I just bought 10 tubes. I figure that should last me through next summer.

I've put a couple hundred miles on my patched rear and it holds air better than my front (different brand tubes).

Patch. Just tossing the tube (aside from a 2" rip or something) is entirely wasteful (and expensive) - I've never had a patch fail. Also, these arguments about blowing out because it's "high pressure" are faulty - the tube is contained inside the tire and doesn't expand much at all (that is, if you don't have a hole in your TIRE and it blows out, which is an entirely different matter).
