Maybe weight doesn't matter in your world but it sure does to a LOT of other MTB users. I keep telling you Joerg; your best bet to get the durability that you say YOU need is to buy a small gasoline powered dirt motorcycle and convert it to pedal power. After all, weight doesn't matter to you. Within reason, of course. There are people who rather ride a bicycle that weighs 10lbs more than customary but in contrast to others they generally arrive at their destinations on time, due to a lack of breakdowns. I happen to be one of those. The only times during the last years (!) that I didn't arrive on time were when I assisted others during repairs. Because they didn't have thorn-resistant tubes et cetera. But Joerg, I ride a conventional steel frame bicycle and I haven't had a breakdown, or even something that came loose so I couldn't ride, in 20 years or more. In fact, in thinking back I can't even remember a time that my bike broke and I couldn't ride it. No flats in 20 years? I didn't say anything about flat tires but I don't judge a flat tire to be a "breakdown" or "came loose" A flat tire without any tools _is_ a breakdown. He get to hoof it out of the wilderness for then next 10-20 miles. But in all the years I've been riding a bicycle I have NEVER had a flat tire that I couldn't fix in a matter of minutes. Way back in the old "sew-up" tire days you didn't even need any tools. Fix it with your bare hands. Now try that with a Gatorskin or a Vee Rubber 700c 25mm. Yeah, it can be done but you won't be able to feel some of your fingertips for a while. I bought a pair of Gatorskin tires, oh probably 10 years ago, and contrary to their advertised proof against flats promptly had two flats in less than 5 Km of riding. I haven't used a gatorskin since. I never use them anymore either. I found them a bit undersized, a bear to get on. The running surface is sturdy and no flats there. Also, one of them made it to a record 2500mi while no others ever exceeded 2000mi by much on the rear. However, all other Gatorskins I had failed prematurely in their sidewalls and that's what makes them unacceptable to me. As for Vee tires, I have the feeling that they are a very cheap Thai made tire or at least I saw some for sale in a store called "Super Cheap" for something like 3 dollars each, so I don't use those either. Just because something is cheap does not mean it is a bad product. No, but it does mean that it is cheap and cheap can be produced by using less than quality materials. I've been told that the cheap tires in Thailand all made from a rubber mix that contains a lot of carbon black, which makes them harder and they wear less and thus are very well regarded by those who can't afford to buy tires frequently. Unfortunately hard tires also "grip the road" less well and have minimal traction. I do not need Tour de France level cornering performance and found them to be quite adequate for riding. Especially the MTB tires because there durability and sturdiness counts a lot more than sqeezing the last tenth of an mph out of a ride. On both the road bike and the MTB I want beefy sidewalls and so far tires made in Thailand gave me that, plus a decent number of miles in terms of wear. I really don't understand this fetish with how many miles a bicycle tire lasts. After all, compared to something like auto tires or egg beaters they are pretty cheap. How would you like it if you had to switch out the tires on your car every 2500mi? Besides, it ain't cheap: 1. SUV, four tires, $70 each so $280 total, 1st set lasted 70000mi and still had half the tread. I only replaced them because they were around 15 years old. 2. Gatorskin, $45, lasted 2500mi at which point the tread surface was at bare minimum. 3. Vittoria Zafiro, $13, 2000mi. Want more? I trust you can do the math. -- Regards, Joerg http://www.analogconsultants.com/ I dunno what you're doing, Joerg, but you're doing it wrong. Compare this to your expensive misfortunes with supposedly "cheap" tyres: 1. Schwalbe 622x60 Big Apples, pair, plus T19A Ultraleigt tubes, pair, total delivered to my door Euro 66 -- half-worn at 8500km/5300m Maybe your riding style or terrain. I tend to always go full bore, whatever the leg muscles can deliver. That ain't wrong, that's my mode of operation because I don't like to go slow. None of my local bike friends milks more than 2500mi out of a rear tire. None. Andre Jute The best is always in the end the cheap option Expensive does always not mean good. Certainly not with bicycle tires. Sorry, should read "Expensive does not always mean good". -- Regards, Joerg http://www.analogconsultants.com/ |

You're doing something wrong. I understand that minimum salary in California is $10/hour, at least my wife's elder sister's tribe that visited last month tell me so. The son, high school education, works part time "unloading trucks at the Dollar store" and says he usually gets 40 or 50 dollars a day. I believe Joerg is an independent contractor. There's no minimum he has to pay himself, he could work all day and end up money behind. But one might assume that if, as a self employed fellow, he is making less than minimum wages it is time to either raise his rates or go to work unloading trucks at the Dollar Shop. -- cheers, John B. |

Maybe weight doesn't matter in your world but it sure does to a LOT of other MTB users. I keep telling you Joerg; your best bet to get the durability that you say YOU need is to buy a small gasoline powered dirt motorcycle and convert it to pedal power. After all, weight doesn't matter to you. Within reason, of course. There are people who rather ride a bicycle that weighs 10lbs more than customary but in contrast to others they generally arrive at their destinations on time, due to a lack of breakdowns. I happen to be one of those. The only times during the last years (!) that I didn't arrive on time were when I assisted others during repairs. Because they didn't have thorn-resistant tubes et cetera. But Joerg, I ride a conventional steel frame bicycle and I haven't had a breakdown, or even something that came loose so I couldn't ride,Â* in 20 years or more. In fact, in thinking back I can't even remember a time that my bike broke and I couldn't ride it. No flats in 20 years? I didn't say anything about flat tires but I don't judge a flat tire to be a "breakdown" or "came loose" A flat tire without any tools _is_ a breakdown. He get to hoof it out of the wilderness for then next 10-20 miles. But in all the years I've been riding a bicycle I have NEVER had a flat tire that I couldn't fix in a matter of minutes. Way back in the old "sew-up" tire days you didn't even need any tools.Â* Fix it with your bare hands. Now try that with a Gatorskin or a Vee Rubber 700c 25mm. Yeah, it can be done but you won't be able to feel some of your fingertips for a while. I bought a pair of Gatorskin tires, oh probably 10 years ago, and contrary to their advertised proof against flats promptly had two flats in less than 5 Km of riding. I haven't used a gatorskin since. I never use them anymore either. I found them a bit undersized, a bear to get on. The running surface is sturdy and no flats there. Also, one of them made it to a record 2500mi while no others ever exceeded 2000mi by much on the rear. However, all other Gatorskins I had failed prematurely in their sidewalls and that's what makes them unacceptable to me. As for Vee tires, I have the feeling that they are a very cheap Thai made tire or at least I saw some for sale in a store called "Super Cheap" for something like 3 dollars each, so I don't use those either. Just because something is cheap does not mean it is a bad product. No, but it does mean that it is cheap and cheap can be produced by using less than quality materials. I've been told that the cheap tires in Thailand allÂ* made from a rubber mix that contains a lot of carbon black, which makes them harder and they wear less and thus are very well regarded by those who can't afford to buy tires frequently. Unfortunately hard tires also "grip the road" less well and have minimal traction. I do not need Tour de France level cornering performance and found them to be quite adequate for riding. Especially the MTB tires because there durability and sturdiness counts a lot more than sqeezing the last tenth of an mph out of a ride. On both the road bike and the MTB I want beefy sidewalls and so far tires made in Thailand gave me that, plus a decent number of miles in terms of wear. I really don't understand this fetish with how many miles a bicycle tire lasts. After all, compared to something like auto tires or egg beaters they are pretty cheap. How would you like it if you had to switch out the tires on your car every 2500mi? Besides, it ain't cheap: 1. SUV, four tires, $70 each so $280 total, 1st set lasted 70000mi and still had half the tread. I only replaced them because they were around 15 years old. 2. Gatorskin, $45, lasted 2500mi at which point the tread surface was at bare minimum. 3. Vittoria Zafiro, $13, 2000mi. Want more? I trust you can do the math. What percentage of your annual income do you spend on tires? What percentage would you spend if you used those oh-so-expensive Gatorskins? I have them on our tandem. I can still afford lunch. You're doing something wrong. I understand that minimum salary in California is $10/hour, at least my wife's elder sister's tribe that visited last month tell me so. The son, high school education, works part time "unloading trucks at the Dollar store" and says he usually gets 40 or 50 dollars a day. I believe Joerg is an independent contractor. There's no minimum he has to pay himself, he could work all day and end up money behind. But one might assume that if, as a self employed fellow, he is making less than minimum wages it is time to either raise his rates or go to work unloading trucks at the Dollar Shop. -- cheers, John B. Joerg makes a little more than minimum wage. Quite a little more. He probably makes more in one month than you made in any single year in your life. |

I really don't understand this fetish with how many miles a bicycle tire lasts. After all, compared to something like auto tires or egg beaters they are pretty cheap. How would you like it if you had to switch out the tires on your car every 2500mi? Well, I use to change tires more frequently then that. Back when I was a high school kid working in the filling station after school. The owner used to give me any tire that the re-capping place refused so I drove on tires with the cords showing. Carried a whole caboose full of tires and got so a wheel change was a 10 minute job. Even with close-to-bald tires on my Citroen I still got much more out of them and this in a country where inadequate tread could result in a ticket. Besides, it ain't cheap: 1. SUV, four tires, $70 each so $280 total, 1st set lasted 70000mi and still had half the tread. I only replaced them because they were around 15 years old. 70,000 miles at $280? that is what? Less than one cent a mile? and you can't afford it? Where did I say that? Just above. You wrote "1. SUV, four tires, $70 each so $280 total, 1st set lasted 70000mi and still had half the tread. I only replaced them because they were around 15 years old." $280 X 100 = 28,000 cents divided by 70000 = 0.04 cents a mile 2. Gatorskin, $45, lasted 2500mi at which point the tread surface was at bare minimum. What sort of a job do you have that you can't afford $45/2500 = 1.8 cents a mile for tires? 3. Vittoria Zafiro, $13, 2000mi. Want more? I trust you can do the math. Sure I can do the math and in my money 45 dollars is 1,440 baht. Which is literally pocket change. It won't even cover a trip to the grocery store. And you are whining about that? Our parents and grandparents instilled a good philisophy in us. "He who does not value the penny is not worth the dollar". I know scores of people who say similar things. "What? You mind the measly five bucks of a morning coffee and pastry at the drive-thru?". Well, I do. Needless to say the folks who lived that way must keep on working until they are well north of 65 and some literally until they keel over. I don't. The problem is that in your grandparents day a penny was money. Today, if you still have 1 cent coins it isn't even pocket change. If you drop one most people couldn't be bothered to bend over and pick it up. Based on what I understand is California minimum salary rates a penny is a tiny fraction of one minute's salary. 10 x 100=1,000 cents/hour divided by 60 minutes = 16.6 cents/minute = 3.614 seconds per cent. If it takes you more than 3.6 seconds to bend over and pick up the penny than you are losing money :-) -- cheers, John B. |

You won't believe how many people in our town still do it, blissfully unaware that $5/workday times two people is a cost of more than $200/month. Then they also go to lunch at $10 a pop and there goes another $400. Then they "need" $50/mo/person smart phone plans, a $100 cable TV subscription, $80 for the gym, new cars every 3-4 years and thus eternally revolving car payments, house mortgaged to the hilt, et cetera. Typically those are the people who can least afford it. Is it any wonder that the average American has net zero savings at retirement age? FWIW, I've done none of those things; and our retirement is very secure. And as I've said many times, I don't have a connoisseur mentality. But I won't ride $15 tires. There are limits. -- - Frank Krygowski |
