My riding buddy goes to China a lot a tells some great stories about sharing bicycle facilities with scooter drivers -- who are displacing bicyclists in China. I've been to China many times and the drop in the number of cyclists is amazingly large. But a large part of the drop has been due to new subway lines. It will be interesting to watch Northern European and Chinese trends for the next several years. I've read some rumblings about user dissatisfaction with bike infrastructure, safety complaints, and some official frustration that the glorious dream of ever-increasing cycling seems to be failing. There are big changes ahead. Bicycles are a wonderful part of it, but won't be *the* transportation solution. Bicycles are a great *part* of that future for all the reasons we know: Healthy "active" transportation (much needed), efficient, low impact, low cost, the rider experiences life immersed in it instead of looking out at it, and (above all,) great fun. Then as us rbt'ers know, there's the learning of mechanics, physics, engineering that we began as kids. The Wright Brothers spirit lives forever! The interesting part will be whether it dawns on people like Peter Furth, John Pucher, Mia Birk and others that high cycling volumes depend on dozens of economic and societal factors, NOT just on the presence of cycle tracks. Ah, but those social factors are encouraged and enabled by butts on bikes. They are substantially dead in the water until the car culture as we know it is rehabilitated. It's actually working in places that are implementing the vision (these places all happen to emphasize bike facilities as a prominent essential - but by no means the sole - feature). Actually altering the culture. (I won't rehash my reasons for thinking that bike facilites are an easily worthwhile, multi-vector array of forces to the post car culture world, even though there are tradeoffs in everything and there is always a valid argument against anything - bike facilites included. And not every facility is worthwhile - even reasonably well considered, but finding things out is messy. Wisdom and alternate perspectives like yours are needed to succeed. But (and I'm no expert on "networking" and collaborating and crap like that), but I don't think we're getting the best you have to offer with, "Every facility is a botched facility." I appreciate your vision. Maybe and hopefully it will be the way in some places; but it's never going to be the way everywhere or most places. Que sera, sera (and I don't mean that in the defeatist sense - rather the realist). Remember, as for myself, whatever I find when I wake up each day is my oyster. No facilities? No problem. I'll ride. So many facilites (most) people can't figure out which way to go? I don't have that particular problem, either. Sieze the day and wring your life from whatever it has to offer. Rock on, brothjer! After decades of demanding bike lanes, these people now realize that bike lanes won't change Podunk into Copenhagen. But they still don't admit that Europe's greater bicycle use is due to immense differences in city density, history, terrain, climate, auto taxes, fuel prices, licensing difficulty, parking scarcity, living spaces, public transportation, liability laws, suburban growth and other aspects of culture. I refer to them collectively as "the enlightened societies". Instead, that crew is now attributing (almost?) all the cycling popularity to one "new" factor: cycle tracks. "Guess what? _Cycle tracks_ will change Podunk into Copenhagen!" Who are "these people"? Furth, Pucher, Birk? Shall we ask them if this is their position? (I'll do it if you want me to.) Of course, it's very hard to get a person to admit they're wrong, It can be, and usually is. That is very true. snip |

I was exhausted trying to keep up with some guy on a tourista bike with panniers. He was a total Frank, taking the lane and signalling and all that stuff. With all the racket I was making, he probably thought he was being chased by the angel of death. When I have difficult-to-bead tires, I also wrestled them on to the bead and/or use soapy water as a lubricant. I like Andrew's idea of furniture polish, so I'll give that a whirl.

They don't buzz that bad on dry pavement, but I agree I don't like it. I'm not quite ready to believe the internet post I read years ago about someone using them as winter training tires - and riding on them with his road club, saying something like "turns a mellow ride into a good workout." In marginal conditions, I only run the front wheel studded - 90% of the control with less than 50% of the drag. I haven't fishtailed yet, but I'm pretty cautious. Think I'm gonna leave the front one on for the freezing rain forecast this morning. Mark J. |

Sad to say, if he was able to stay ahead of you, he probably wasn't a _total_ Frank. :-( At least, not any more. I ride my former (pre-retirement) commute route only occasionally these days.

I ride cheap Innovas that I got from Bicycle Tires Direct (and which they no longer carry). http://www.jensonusa.com/Bicycle-Tir...9-Studded-Tire I use them so rarely, that I couldn't see spending serious money. I've ridden the last couple of days on my regular commuter bike with 28mm tires. It's been frosty, but traction has been acceptable except in some places (which I ride with extreme care). I typically don't take the bike with studded tires unless I wake up to snow or serious ice. If the freezing rain actually comes tonight, I'm screwed. -- Jay Beattie. |

They're convinced they can't safely ride on even narrow back streets without a paint stripe that tells them to skim the parked cars. The recent (and ongoing) protest in London was and is almost completely opposite to that. The problem is the high proportion of the deaths that have occurred on poor quality infrastructure, and the need to either scrap it or sort it. The worst example (Bow interchange) has been made significantly MORE dangerous by the cycling infrastructure, and the latest way of "fixing" it was to make it far more difficult and dangerous to use the safer alternative. I've got no problem at all with criticizing or protesting badly done cycling infrastructure. Our local bike club has attempted to do that with one particularly crazy situation, spending serious time in meetings with the offending agency. Unfortunately, we've had only small success in correcting it, partly because there were other cyclists phoning in who said "Oh, I love the new facility!" That's despite guideline-violating collision hazards, written and verbal testimony from nationally known experts, and one cyclist made quadriplegic. Regarding London protests: I've been watching British press on this for quite a while. The message through the press has not been so much about any specific aspects of the design (Bow or elsewhere), but instead about "Six cyclists killed in two weeks!" and "Cycling in London is too dangerous!" and "We need Amsterdam facilities!" (Well, I supposed cycletracks are a specific request, but I tend to doubt they're realistic in London. I'd like your thoughts on that.) Perhaps cyclists are proposing workable designs for specific problem situations, and the press doesn't communicate that very well. But from what I've seen, the "Danger! Danger!" gets trumpeted far more than any "Here's a solution." BTW, this proposal from Edinburgh seems to have potential: http://www.scotsman.com/news/transpo...sons-1-3231777 .... although I'd also like strong publicity campaigns telling cyclists to stay out of truck blind spots, particularly at curb side. As with doorings, the legal fault may be with the motorist, but a cyclist is not wise if he trusts motorists to avoid him when he's nearly invisible. - Frank Krygowski |

A Priest, a Doctor and an Engineer are playing golf and the group ahead of them is playing slowly and holding them up. they complain to the Starter and he tells them that the group is some blind fireman who lost their eyesight fighting a big fire and rescuing some people and the golf club has allowed them to play because thy are heroes who gave up their sight in order to save people. The Priest says, "I'll pray for them". The doctor says, "I'll get my buddy, an eye doctor to se if something can't be done about their seeing". The Engineer says, "Why can't they play at night?" If there are too many deaths due to cycling in London the problem can be solved by simply banning bicycles in the metropolitan area. -- Cheers, John B. |
