Yup, I have puncture resistant tires and I still carry spare tubes, pump, tools and a patch kit.

Be careful, the current geological science suggests that petrolium in its various raw forms has nothing whatsoever to do with ancient swamps, dinosaurs, or anything of the kind. There appear to be continuous, deep geological processes that are producing oil. No swamps or dinosaurs appear to be involved.

Oil is made from plankton(alive and well and lives in the sea) according to most sources.

Too broke or too ignorant, in equal measure? I discovered how bad it was while I was looking at used bikes. While some were probably scammers trying to mask other problems, many seemed completely honest but just never bothered to buy pumps.

I often wonder about the low seat thing, but I think it is a result of lack of confidence. My kids like their seats much lower than is 'correct' because they don't want to feel like they can't put their feet down without dropping off the seat.

He is a year round commuter who does 15+ miles a day commute. He carries no spare tube, patch or pump. Nothing more than a brown bag lunch and a water bottle on a bike with a semi flat tires. I look out for this guy and do a quick check of his bike whenever I can for him. The last time I did that, his brakes were very loose and I had to tighten it up for him.

There are some stuff in life I will never understand.........
If you are constantly fixing and adjusting their bikes, whats the incentive for them to?

Although I would love a coworker I could go to for help with my bike. How much do you charge and do you make house calls?

I feel neglecting if I am a underinflated by only a few pounds. It is rewarding to have optimal air pressure because of how easily the bike rolls.

The same goes with car tires, so many people neglect their tires by running with dangerously low pressure, this is such a waste of fuel. My truck tires have exactly the right pressure or even 1 pound more.

I know what you mean, but this coworker is not the smartest in the world. He's a janitor, speak very little English, but very kind and offer us food from home for our help. I, and along other coworker sometimes worries for his well being. We tried teaching him some mechanical stuff but he just do not have that learning thought process even if it means something that might be a safety concern.

You would be able to cop a feel on my aluminum cross bike, but ( at 30 lbs ) you'd have to tell her she's not heavy. You'd never be able to feel my carbon road bike up, though, because she doesn't like being tied down with locks, and doesn't go outside without being closely supervised. If you did, though, Gazelle would tell you that her tubes are hard as nails, the better to roll up hills. Bestla ( the giant ) would point out that her 28s are a bit more relaxed, and let her prance over dirt trails that would stop a road bike in its tracks.

I see far too many on under inflated tires. If time permits, I will stop the rider and offer a pump or two. Usually, the rider is an non-English speaking immigrant who is more than grateful to receive my help and will smile like there is no tomorrow. If I see a young dude trying to be "hip" on his recycled 10 speed, I will simply tell him to pump it up in the front or back. One day my friend and I went for a 10 mile ride and came across a guy who was huffing it like the police were chasing him. His rear wheel was FLAT. I told him about it and offered a pump or two. He was unaware and refused and kept up with his chase. Unfortunately, the next day one of the bikes we rode had TWO FLATS.

While we're at this, lets not forget those riding a bike to the sound of a hundred tiny mice, all squeaking their heads off! A can of lube isn't that expensive, and a lot cheaper than a new chain.


I have come to the conclusion that the vast majority of the population is oblivious, and incapable of logical thought processes.

Heck, I found two of 'em on my bike yesterday. Then after I pumped up the rear and gave it a spin, the rim started dragging against the brake pads. I'll have to dig out the spoke wrench in the morning.

He's referencing an alternative hypothesis with some support; the current consensus is still that the vast majority of our oil comes from squished plants.

So where did the hydrocarbons on Titan come from?

i like my tires like i like my women: skinny, hard, and 23.

/pressure policing isn't as effective outside roadbike crew because most of the fat tire brigade have few problems with snake bites/pinch flats...speaking comparatively of course

Answer #1: From all the dead, half-cocked theories about how humans have nothing to do with climate change. Er, I should say that the theories are at least dead to realistic, logically thinking people w/ any understanding of science. Sadly, that doesn't always equate to changes in thinking on the part of big business and politicians... not to mention a sizable portion of the US population.

Answer #2: From all the oil that Europeans has saved by actually internalizing/pricing in a lot of the environmental costs of oil consumption in the form of higher gas taxes.

You must be mistaking me for a researcher in either exogeology or petroleum science. I'm reporting what the current scientific consensus is. There is some support for the abiotic hypothesis, but it is not the currently accepted consensus.

Hope this helps, please stop confusing nice people.

You could make up some business cards offering a "repair" service to make their bike 20-50% more efficient for $5. If you feel bad taking $5 just to pump up their tires and adjust the seat, you could offer some pointers too (like which side of the street to ride on).

after many years of cycling i did my first charity ride this past weekend- i couldn't believe how many
people showed up with bikes that had near flat tires. the on-site bike mechanic spent quite a bit of time
inflating and telling people how the bike they were riding was either too small or too large or the seat was at least
8 inches too high or too low.
i overheard the mechanic tell one guy that the stem on his mountain bike was up so high it was in danger of breaking off
during his ride since there was only a couple of inches left in the head tube. the mechanic said it was a huge safety issue
the rider told the mechanic "i've ridden 10 miles so far this year and nothing has happened, just leave it be, besides if you lower it my back will hurt"

Make sure to check those tires.
