The major problem with the Internet these days is that people mistake opinions for knowledge. Even the media now has eschewed knowledge for opinion. It's Usenet -- no one vets your palmares, no one vouches for your bona fides. But every reader can decide for him- or herself whether a post is sufficiently useful/interesting/entertaining to read. Hostility can be both unrelenting *and* entertaining, but it's tough to keep that up for 20 or 30 posts a day. Look at Andre, a man hardened by years of payment by the word, see how he paces himself. I'm not all sure that years of reading Usenet have been time well spent, but I have learned a thing or two. One is that, although I devoutly hope one day to retire while still able to ride a bike, a person *can* have too much free time. The other is that if doing or reading something makes me crazy, it's better to give it a rest. -- I don't follow you. What does "palmares" have to do with anything? tech is not who you rode with, what you rode and why you rode it. If you cannot see what works and what doesn't than why in hell would you be on .tech to begin with? Surely you might not understand a point or a necessary repair, but if it is explained to you and you cannot verify that it is correct simply by trying it, then again you haven't any place on .tech. I have never seen any addition to the group from John or Frank and Ridesalot. To them this is nothing more than a social group. By golly, you are right! "Tech is not who you rode with, what you rode and why you rode it, If you cannot see what works and what doesn't than why in hell would you be on .tech to begin with?" But of course you just posted: "I arrived home after 39 miles, 3,500 ft. of climbing and logged it. Just over 2,000 miles and just over 80,000 Ft of climbing. I guess that keeping track of that sort of thing insults Frank whose idea of a ride is down to the village and back." So perhaps you could give us some more details about the "see what works and what doesn't" that you just furnished in that thrilling tale. -- Cheers, John B. |

There was a thump with every revolution of the front wheel. I was going to ask someone to borrow a pump. Then I noticed that there was no valve. They must have been using airless tubes or perhaps they filled the tire with expanding foam. Terrible bike but a nice ride on the 21 km long carless Danube Island in the middle of the Danube River. I guess it's understandable why a Bike Share company would opt for tires with solid tubes. |
