Lance Armstrong shows to to change a tire in 1,5 minutes.

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

If if puts the amount of effort he put into his seven tour wins, into rehabilitating his public image, he will succeed at that as well. This video is a small step toward that goal, and I think it's quite effective at re-humanizing him to the public. I could easily see the guy running for elected office some day, and with his competitive drive I think he'd absolutely crush most lower tier garden-variety politicians.

EDIT: Looks like we have less time to edit our posts now, before the "edited by" flag comes up. Dang!

He'd make a great politician. He has the lying and cheating down to a science.

Cycling's most infamous rider has been looking for work lately. We caught up with him at his latest bike-shop gig to hear a few pointers about what to do when you break down.

So they're made up, some are, but there is also consistency in number of sites reporting the same figures which all lend support.

Greg Lemond can fix a flat, too. Even if his pump breaks.

Yes.

Tube failure where the valve stem connects is likely when you leave the nuts off. Without them the valve stem moves when you attach and remove the pump, causing the rubber to fatigue and eventually leak.

I know a cyclist who isn't a perfect human being, ground his lawyer tabs, bunny hopped, and was off the bike for almost a year. Forgot his QR. Very experienced rider, tour leader, etc.

I once had a tire go flat due to valve leakage. Caps keep the dirt out. I also like colored ones. Easier to find when changing a flat.

I'd like to see Lance with a modern rim, one of those "ready for tubeless" jobbies. Last rim I bought wasn't even advertised as such, but oh boy. My thumbs took a couple days to recover, blisters even. Used tire, too.

Carry a spare tire, never lose time looking for the cause. Bikes go pretty far in 5 minutes.

Road Morph G - never have a friend rip your valve out again.

IMO they're really only necessary on old-school rims with a very narrow tyre well, where tyre pressure is insufficient to push the valve all the way home because of the stiff section of tube around the valve.

I've seen plenty of tube failures at the edge of that stiff part due to the tube ballooning into the tyre bed, but maybe only one or two of the sort you describe. I'm not likely to wear out the base of a valve myself, since I use fittings that thread on rather than push on.

Also, valve nuts look like arse on anything but a box section rim, unless maybe you pinch the profiled spacers from some tubeless valves.

That doesn't happen, rubber doesn't fatigue. Those lock nuts are useless.

Worse than useless, when you have a puncture on the roadside and the stupid nut won't come off.

Rubber fatigues.

FACTORS THAT AFFECT THE FATIGUE LIFE OF RUBBER: A LITERATURE SURVEY as published in Journal of Rubber Chemistry and Technology

In this case, it could also have been abrasion but didn't look like it.

Those lock nuts are useless.
That's what I suspected, so I left them off when they didn't look good on a new set of wheels I built with Velocity Fusion rims narrowing to a thinner edge aerodynamic edge than the classic Open Pro / Reflex clincher / MA40 box section rims I'd been riding for years.

The Continental Race 28 tubes failed within a couple of weeks of each other where the stems attached which I'd never seen since getting a bike with Presta valves.

With nuts, the following tubes from the same batch had no problems and everything has been fine for over 20,000 miles.

The connection was clear although I don't know what the other causal factors are - tube brand/model, tire volume, rim bed shape, rim depth, hole clearance, pump chuck weight, pump hose weight, how much the chuck moved when clamping it on.....

Conversely, I've never had a nut get stuck, just come loose and rattle annoyingly until tightened.

Your mileage may vary.

Rubber fatigues.
Let me rephrase: rubber in a bicycle tube will not fail from fatigue in normal use. It's not stress cycled enough. It is possible, however, that a tube will fail at the valve stem from abrasion by a rim that has too large a hole—or a hole that hasn't been adequately de-burred and chamfered.

A stuck nut can happen when you finger-tighten it down after inflation, possibly in the hope that it won't rattle, then a puncture occurs.

The one positive feature of a valve nut is to keep the valve stem from disappearing into the rim when a pump head is pushed onto it. I've never found this to be a useful feature.

Ironically, valve nuts most useful on Schrader valves since they require more force to get a quick-release pump chuck to seat, but most Schrader stems aren't threaded at the base and therefore can't use the nuts.
