12/8 http://latimesblogs.latimes.com/lanow/2010/01/cyclist-sentenced.html Car driver gets 5 years for assualting bicylists with car. \_ How many years do cyclists get when they run red lights? I almost hit one last week when a cyclist ran a red light in front of me while I was about to start moving on my green light in Fremont. \_ How many years do motorists get when they run red lights? I almost got hit by one last week when a motorist ran a red light in front of me while I was about to start moving on my green light. (true, btw, not just a tongue-in-cheek copy of the pp) \_ True, but most people would (correctly) assume that it's the driver's fault if you did get hit. \_ How many years do car drivers get for speeding? As far as I can tell, every car driver breaks the law. And speeding kills far more people than cyclists running red lights. The real difference here is that a cyclist running a red endangers himself, car drivers endanger everyone. Don't get me wrong though, I think both cyclists and car drivers should obey the law. But the penalty for running a red light or speeding should be much less than for deliberately assaulting someone with a deadly weapon and causing great bodily harm. \_ But the problem is that when a speeding driver hits someone/something, people naturally assume that it's the speeding driver's fault; whereas when a driver hits a red-light-running cyclists, people naturally assume that it's the driver's fault given the current politics unless the driver can prove that the cyclist ran the red light which is hard to do unless there is a witness or a camera at the intersection. -- PP \_ Man, what city do you live in? Here in San Francisco car drivers who hit cyclists are almost never even cited, even when there are multiple witnesses to them being at fault. http://sf.streetsblog.org for many examples. \_ Fremont. -- PP \_ I've been hit on my bicycle by cars 3 times and all 3 times it was the drivers fault. All three times they didn't even bother to get out of the car. The last one hit me from behind, launching me over the car in front. The woman driving, yelled "your fault", turned up her stereo and drove off. We've created a society where people are too afraid to be concerned. \_ I'm Spike Bike. I hate cars. \_ Too afraid?

7/29 I have a 70's road bike I ride to work. A few months back I replaced the rear wheel and tire, then I put a set of old 70's rear baskets on it. The baskets are great in general, with them I don't have to wear a backpack and I can carry a lot more. However, they are heavy. Since I put them on 2 months ago I've had 3 flat tires in back, compared to 1 in the year previous. I think the extra weight is wearing out the tire faster and causing more flats. Do I need a tougher tire or something? What can I do? \_ For commuting, extra weight shouldn't be a big deal, so use heavy tires. I've been very happy with Specialized Armadillo tires, but I'm not sure if they make really thin road bike styles. Mine is 700C size. \_ Extra weight will cause more flat tires, not because it wears them out faster, but because there's more force on the tire when you run over glass and thorns. (That's also why bikes get more flat tires on the rear than on the front). For commuting with weight, you probably want to get a fatter tire designed for commuting. If your wheels are 700c, look for a 700x32 or 700x35 or even 29" slick tire, depending on what will fit in your frame. My favorite is the Schwalbe Big Apple 28x2.0", but there are a lot of decent commuter tires. If you have 27" wheels, as a lot of bikes did in the 70s, your selection will be a lot more limited, but you can probably still find something better than what you have. -tom \_ I have 27" wheels. I think I have a little more clearance for wider tires, but not a huge amount. Are you saying I could put wider tires on the same wheel I have now? My local bike shop also has 27" Aramdillos for $45. \_ Yes, you can put wider tires on your existing rim, if they'll fit in your frame. The Armadillos seem pretty good; get the widest size available (if there's a choice) Also, make sure you have enough air in the tire; if your tire is too low, your rim will bottom when you hit potholes, giving you pinch flats. -tom \_ Hmm. Googling around I haven't found any 27" tires wider than the 1 1/4" tires I'm currently sporting. \_ Like I said, the selection of 27" tires is pretty limited; these days rims are pretty much not made in that size. -tom |

You're trading TIME for SPACE. Nothing comes for free. If space is a PREMIUM like my little apartment, this is a really great thing to have. By the way, I commend you for riding bicycle to reduce our carbon footprint. Moving 200 pounds instead of 3000 pounds reduces pollution and our dependency on foreign oil. Kudos to you! Lastly, how do you CCW when biking to/from work? \_ I've just been hanging it from the front wheel via a big hook. Is that bad? \_ It is if you leave it like that for any amount of time. \_ How long is "any amount"? \_ Dunno. But I left a bike like that for a few months and it totally deformed the front wheel. \_ Huh, I left it that was for months and... the wheel was still deformed. I guess it's hard to tell when your wheels are already way out of true. \_ Hanging your bike by a hook shouldn't throw the wheel out of true, if there's a reasonable amount of tension in the wheel. -tom \_ It was a pretty shitty bike. Shrug. Now I just avoid hanging my bike by a hook. \_ I've hung lots of bikes by two hooks and never had a problem. I could imagine if you have a really heavy bike then hanging off one wheel may not be a good idea. Two should work, if the bike doesn't deform itself just riding around under its own + your weight already. |

You'll still get flats. -tom \_ Of course you'll still get flats. The question is if you will get fewer flats, and if these extra work/expense is worth the reduction. Personally, I have never found slime to be worth anything. I didn't even notice a reduction in flats when I tried it. -jrleek \_ Do I need to spell out "I have tried a whole lot of different flat-reduction products, and have not found the reduction in flats to be worth the extra weight, expense, and wonky handling"? I thought that was implicit. -tom \_ Well, I was looking for more info than in your first response, so I was hoping you'd elaborate (which is why I asked about armadillo). I guess I shouldn't have been surprised at your hostile response. Do you actually interact with people in real life? -op \_ I rarely interact with anonymous cowards in real life. -tom \_ So? You were a jerk to me too. -jrleek \_ Reciprocating. -tom \_ In tom's world, all people have wronged him, so he's always justified in smacking any random person in the face. -op \_ What the hell is wrong with you people? Do you weep uncontrollably on BART when people give you mean looks? Tom just gave his opinion on shoving goo in your bike tires after you asked. Grow thicker skin please. \_ No, most of them are too misanthropic to ever ride BART. That is why they live in the suburbs, so they don't have to interact with potentially unpredictable strangers. \_ No, most of them are too misanthropic to ever ride BART. \_ The most effective thing you can do to prevent flats is to inspect your tires frequently. Look closely at the surface for things that are embedded in the rubber, or little cracks that have picked up debris from the road. Most flats don't happen suddenly; they happen slowly as road debris gets pressed through your tire, then gets pressed into your inner tube. Before you go for a ride, check your tires. Every square inch. Look closely. Pull out that staple, dig the grain of sand out, remove the chip of glass. If you're doing this, then tires made of slightly thicker rubber will make a difference (I ride on Vredestein Fortezzas, but my tire selection is somewhat limited by my wheel size -- 650C). --alawrenc \_ Do you ride a triathlone bicycle? \_ No, I ride a recumbent. --alawrenc |

I'm actually using my mountain bike in SF now and I bought some panniers but the metal loops that hook onto the back of the bike rack thing are so tiny as soon as I hit a pothole they fall off the bike. What's a good one to get that has long loops so they won't fall off the bike? I don't know why this is so hard, in Europe the loops are about 2-3 inches long and much bigger so there is never an issue -eric \_ Generally panniers have some sort of elastic cord which attaches to the bottom of the rack and keeps them in place. Yours don't have anything like that? -tom \_ I was wondering how that worked -- thx tom very helpful -eric \_ losing weight helps too. \_ Um, what? When they are empty they are most likely to come off. \_ oh, nevermind. I thought it was a case of the thing (pannier) being too heavy hence they fall off. Then again, I have no idea what a pannier is. I hate bikers, and I hate the SF Mass Chaos, it's making SF as unpleasant as LA to live in. \_ Move.

Are you trying to disingenuously portray this as "kids who dont know better" than a common problem among adult cyclists. Look at the number for intoxicated cyclists. Why are you trying to disingenuously portray this as "kids who dont know better" rather than a common problem among adult cyclists? \_ Because most injuries to adult cyclists in bike-car collisions are caused by driver errors. There have been numerous studies on this subject. -tom P.S.: I should note that, while the three most common bike-car collisions involving adults (the right hook, the door, and the left hook) are all legally the fault of the driver, good cycling habits can help avoid all three.

3/9 If I get a few moving violations from my motorcycle, will it affect my car insurance rate? What about the reverse? Just curious. \_ hell, getting violations on your bicycle (for which you need no license) can affect your rate. \_ So I have always wondered about this. What if when the cops pull you over on your bike, you refuse to give them your driver's license? You are not required to carry ID, are they just going to arrest you for not being able to prove your identity? Perhaps when you bicycle, you should carry an ID other than a driver's license. \_ People like Tom just carry a California ID, no big deal. You know not everyone in the state has a driver's license. \_ If they are pulling you over for a moving violation they have the right to know your identity. If you can't give them some proof that you are who you say you are they have the right to take you in to determine you identity. It isn't being arrested though. \_ This is basically correct. One thing I am not sure about is whether bicycle moving violations show up on your driving record. Cops say that a fair amount, but cops generally have little idea what the law is, and I haven't been able to find any code which is explicit on the matter. It's hard to believe that a 14-year-old who gets a ticket for running a stop sign on his bike would start with points on his driver's license. I'm relatively certain that motorcycle violations would show up, though. -tom \_ I would argue from a practical implemntation standopint that they would. Bicycle violations are so rare that I think the state wouldn't bother differentiating them from normal motorized vehicle ones in their record keeping and processing methods. -ERic |

What's happening now doesn't work. I don't think I support as many of those as bikers would hope, though, but why not have some small percentage devoted to bikes? \_ There are plenty of trail-sharing plans out there (such as odd-even days); the problem is that the anti-bike crowd doesn't want to share trails or give any access to bikes. In most places it works just fine, it's only in California that it's still a big problem, and that's due to the actions of a small handful of NIMBY, "we were here first" types. -tom \_ I think it's because of the actions of a lot of reckless riders, many of which I have encountered. \_ Bikers don't want to run into hikers any more than hikers want to get run into.

What's wrong with Schrader valves? -jrleek Why do I need Presta valves? -jrleek \_ I have a foot pump with a gauge already. And I'm happy with Schrader valves, but I'll take your advice into consideration. The comments about Presta I've seen suggest they're important for narrow tires, and that tubeless mountain bike tires use them. Okay, I don't have either, so I'll stick with Schrader. -emarkp \_ I don't care what valve you use, but I'd recommend just buying a cheap set of non-knobby, narrowish tires if you are riding on the road. Why would you use wide tires? \_ I agree here. Riding on skinny tires is so much easier. On the other hand, if you want a workout, I guess big tires may be good... \_ In San Francisco at least, with all the train tracks and the rough roads, I feel more secure on wide tires. Maybe this is foolish, I don't know. -!pp \_ Well you don't need super-skinny racing tires. Are yours knobby? I think even if you want fatter tires you can use semi-slick or slick ones. Knobs are probably the biggest energy drain. \_ I prefer the wide semi-slick. Primarily because on the side of the road there can be lots of debris, and the wide tires seem to do better with fewer flats. -emarkp \_ Yeah, mine are knobby. Thanks for the info, I think I will switch to some big smooth ones. \_ If you're on the street, get semi-slick. \_ Presta valves simply work better with hand pumps. Having to press in the valve stem isn't a problem when you're using a high-pressure air compressor, but if you're using a tiny hand pump it is sometimes impossible to fill the tire faster than the air leaks out. On the question of tires, wide slick tires are what I would recommend on a commuter. The Schwalbe Big Apple is a great tire, but there are plenty of others. I don't think you need tires narrower than 700x28 unless you're specifically riding for speed. -tom \_ I carry a foot pump in my saddlebags, so I don't care about the resistance of the valve spring. But since the pin on a pump depresses the spring, why would the Presta give any advantage there? -emarkp \_ The ability of the pin on the pump to depress the spring depends on the geometry of the valve stem and the pump; it is far too common to be unable to pump up a Schraeder valve tube with a bike pump, and it's especially a problem when the tire is flat, making it difficult to have the leverage to get the pump on the valve stem. The Presta is just more robust for the application. -tom \_ That makes perfect sense. I've done my roadside repairs before, and agree that it sucks to have a hand pump, and can see that the Schrader could be more of a problem, but haven't don't the roadside fix experience with a Presta valve. That's why I started carrying a foot pump with me. On the other hand, if I were offroad, I wouldn't want to be lugging saddlebags. -emarkp |
