And when fatalities per mile are computed for non-freeway car travel, the result is much closer to that for bike travel. Furthermore, if you were to compute fatalities per mile for non-drunk law abiding bicyclists, I'd bet it would beat the car rate for non-freeway travel. No. We are talking about using the _existing_ infrastructure. For cars it exists and for bikes it largely doesn't in the US. Almost every street is a bicycle facility. It's unfortunate that people like you pretend that isn't true. Many streets are not safe for cycling. It is also not exactly fun to ride on the side of a county road while noisy vehicles zoom by at 60mph and some spew a copious amount of Diesel soot into your face. Why would anyone deliberately want to do that if they have a car? But Joerg, the State Laws that I've read all essentially state the same thing, that a bicycle is a vehicle and a vehicle has the right to use the public roads. Yeah, AFRAP and when you get smacked by a car the driver will claim you "suddenly swerved" unless you have an ironclad witness situation. Even then it didn't help the people who died or now suffer longterm health impairments. But I've been ridding a bicycle since I was 12 years old, certainly not every day and when I was working in the jungles I certainly didn't ride, but for all that I've never been hit by a car. And, in fact, I have never personally know anyone who was hit by a car while riding a bicycle. Not that it doesn't happen but simply that it is rare enough that no one I've know has. Exactly, if it didn't happen to you and your friends you were lucky. I know several who got hit, badly. Why, simply because you are riding a bicycle, do you believe that the tax payers of your state/city.town should be burdened with the cost of building an infrastructure for your private use? Some (few) politicians have the smarts to see that this will foster a healthier community because then lots of people start cycling. I ride here despite a lack of infrastructure but the vast majority of potential cyclists does not. Even seasoned road bikers don't, they cart their bike to the valley and ride there. Of course, this requires smart enough local leaders which we don't have. You must smoke funny cigarettes, or something. In every society I have lived in or have read about, people strive for an easier life style as the eco,nomy grows and one has greater income. China, for example, the swarms of bicycles that existed 20 years ago are no longer there. I've lived in several developing countries and in every one as the economy developed and people became more affluent bicycle use decreased, That is because the government there has adopted something similar to what the Hungarian called "goulash-communism". Almost laissez-faire style on a local level. Now they finally realize that some of this was a mistake. As evidenced by events like where a pilot of a business jet needed three attempts to land in Beijing because of dense fog, only to find out that this wasn't fog when he stepped out of his aircraft and almost coughed his lungs out. In fact in the Netherlands, that wonderful haven of cycling now has contested city roads. Rotterdam is even listed in one of the "Worlds Most Congested Cities" that I recently read. Building bicycle trails isn't going to create a great new cycling world. Where there is a will there is a way: http://www.eltis.org/sites/eltis/fil...g_strategy.pdf If we do nothing then nothing will happen regarding mode share. The question we have to ask ourselves is whether we truly want to increase cycling or just let it be. In most areas of the US it seems the latter is the case. -- Regards, Joerg http://www.analogconsultants.com/ |

He said, "This. My brake levers are all the way to the handlebar". Now that was on a bicycle that had had the brakes adjusted by two different good bicycle shops. My buddy had so much trouble with his disc brake that he ended up swapping them for V-brakes. Since then he's had no trouble with his brakes at all. This is proof positive that disc brakes are inferior to rim brakes. ;) VB EG LOL As I mentioned previously, we recently hosted a very experienced bike tourist. His rig had disc brakes. His complaint was that on one not-so-long tour, he was suddenly without brakes. Apparently the pads had worn down, and unlike with caliper brakes, he couldn't pop into the closest Wal-Mart and buy new brake shoes or pads. Not that discs don't have their benefits. But one does have to separate the hype from the practicality. In Joerg's writing, there's always a lot of hype. Was he on mechanical or hydraulic discs? If I were touring on discs, I'd take some pads along, and with mechanical discs, you do get a warning that your pads are nearly worn out. The return spring sandwiched between the pads will start pinging on the rotor. Hydraulic discs are more fussy -- great braking and no manual pad adjustment, but I don't know if that outweighs the inconvenience of dealing with hydraulic fluid. I was initially concerned about that, bleeding them and all that. Turns out I didn't even have to get a bleed kit. When I feel a levers becoming a bit "spongy" I just open the reservoir, burp that brake for a minute or two, top it off when no more bubbles appear, close it and carefully clean it because DOT-4 fluid is a bit aggressive on paint. I had to do this twice over three years which I'd consider not too onerous a maintenance requirement. ... Even on a loaded touring bike, a mechanical disc provides plenty of stopping power -- as do various rim brakes. The calculus is different for MTBs. Rim brakes are not as quick-stopping in wet weather and are certainly harder on rims, but I wouldn't bother with discs unless you're riding in a lot of rain and muck. On trail rides creeks and puddles are a problem. It's not so much sharp bends or steep hills that then cause an issue (you could always slow down, it's not a race) but in my case mostly animals. No idea why but many of them jump into the trail without looking. The closest call was with a young buck. He crossed right in front of me, probably never saw me and then kept on galopping as if on a mission. He never turned around even though he must have heard me with the gravel flying and all that. With rim brakes we would have most likely collided. ... I do that, so I have discs -- and like them. If I had to go back to rim brakes, I'd be fine. I was fine for the 40 years before I got discs. I'd probably just be grinding down more rims. That's the other problem. The rims on my old MTB had nasty grooves after just 1000mi. One could carry an extra bottle of water and a sponge, then stop after every muck crossing and wipe off the rims. "Honey, sorry, I'll be late for dinner because I just ran out of muck cleaning water and have to find a clear creek of something now". -- Regards, Joerg http://www.analogconsultants.com/ |

For example, those are used when machine section alignment or exact sprocket line-up cannot be guaranteed. http://www.directindustry.com/prod/r...86-290844.html Quote "Extra clearanceTrans-Flex® chain is designed for severe duty applications, such as in transit mixers, crawler drives, and other uses requiring delivery of full power despite recurrent sprocket misalignment. ULTR-O-LIFE™ O-ring roller chain Uses square cross sectional O-rings to seal in special lube while sealing out dirt, moisture and other contaminants". For cycling there would have to be more R&D and O-rings are probably not the best option. Possibly sliding multi-layer PTFE gaskets are the ticket for lower friction loss, who knows. Usually problems like that can be solved. It is not something that could be marketed to racers or weight weenies, more to commuters and most of all the more hardcore MTB riders. Once I saw a group who had very dirty MTBs on their truck in front of ... you guessed it ... a pub. I was riding mine and it was full of mud as well. So we talked shop. They were very surprised that I got 50 miles out of one lube. They said theirs usually sound horrid at 30-35mi. -- Regards, Joerg http://www.analogconsultants.com/ |

You of all people don't see that? Folsom increased the mode share from pretty much zero to somewhere between 1-2%. They did that by massive investment in bike paths and in contrast to when we moved here it is a joy to ride there. Now do the math and figure out the health benefit to their society. Actually, neighbor communities like ours benefit for free as well because now people ride there. Manhattan was another success story where it even increase business for restaurants and other such places, big time. In America you will never get above 10% except in very isolated cases and then only for young people. It's still worth it, even if just for the health benefit. -- Regards, Joerg http://www.analogconsultants.com/ |
