    Mogoče prešaltaš na drug šport.
    Ne zanima me tolk materijal , ampak to kako spretno in zame estetsko dovršeno je naprimer skrit krmilni ležaj. 
    Pač če te ne zanima se ne javljaj , itak kot praviš nimajo nobene vrednosti.

    Lucidnost nas na tem forumu..

    Marsikaj lahko zapišemo..
    Med vrsticami pa kdo razbere tudi bistvo..
    kaj bi bilo če bi vsi razumeli..? ;)

    Za "tradicijo" v kolesarstvu mi ni treba skrbet, verjemi mi Tex. ;)

    ...sledi tudi "poravnava poti", ko postopoma (pre)nehaš komplicirat... in samo pelješ... in posledično resnično zadovoljstvo pride čisto od drugod...

    Na karbonski, na alu konfekciji, ali pa na "žlahtni" železnini...

    Ne igra nobene vloge več... ;)

    "Poravnava poti" mi zveni tako nekako premocrtno. :) Zato mi je prispodoba ...come to a full circle... sklenjen krog... bolj pri srcu. Ko si po letih sanjarjenja koncno kupis to, o cemer si sanjal ali pa koncno spoznas, da ze VSE imas, ja, nehas komplicirat' in se samo vozis, si srecen. Bravo!
    Pomembno pa je, s kaksnimi izbirami prehodimo to pot. In da v njej tudi uzivamo. The chase (of the dream) is also part of the fun. :)
    Krog je sklenjen, hkrati pa, pozor!, vcasih vzklije novo, se nezavedno pozelenje. In, gremo maratonci v naslednji krog, cikel, bi-cikel... :)

    Nekaj odlomkov intervjuja iz revije Peloton st. 69 / few excerpts from James Startt's interview with Tom Ritchey

    Tom Ritchey likes to say: "Steel is as old as the sword, the hammer or the spike, but it also goes to the moon." Ritchey is nothing short of a pioneer in the cycling industry. He built his first bike when he was barely a teenager, reconceived bicycle tubing and was one of the founders of mountain biking. Today, he produces top carbon components, but he never forgets the lessons learned from steel. Ritchey can be outspoken and critical of the industry, but in the end he simply demands that it lives up to the same standards he places on himself.

    ...
    To be honest, when I look back, I just have to say that it was such a different time. People had a different relationship with their bikes. The mindset during that era was just different. All of the racers worked on their own bikes. People built their own wheels. People built their own bikes. People understood their bikes. The mechanical aspect of the bike was very much part of the racing experience.

    But I’d also built about 50 tandems without lugs and, of course, those frames require a really strong structure. To do it right, tandems required oversized tubes and superstrong forks. There was quite a bit going on in tandems. Strength is No. 1 with tandems and they have been central to a lot of design decisions I’ve made as a frame builder.

  • 1 |-10+11

    Your steel Logic frame has been a fixture of the company for years. How has it evolved? Well, in the 1980s, road racing was still about steel but things were starting to change dramatically because of what mountain biking was bringing into the sport. Big-tire biking with suspension forks and aluminum tubes was very popular. Companies like Cannondale were the real darlings of the industry, with their unique oversized aluminum look. But there was a lot of immaturity when it came to concept and design. A lot of the new people didn’t understand things like Q-factor, ergonomics and the biomechanics of the rider’s position.

    Yet there was the economics. Cannondale came out with a frame that probably cost 25 dollars—a frame with big tubes—and it was a huge marketing success. It really took the industry off guard. They took that same frame and used it across the board on probably all of their bikes. All they did was change the components. That had never been done before. You would never take that business approach if you were in the industry for a long time and been using quality steel tubing—to think that you could take the lowest manufacturing process and just hang different parts on it. But Cannondale did that and they had incredible margins. And then the big down tube provided a huge new billboard for the brand. And with industry-wide insecurity, the billboard size of a down tube became the new standard. All of this created the dawning of the aluminum era that was not based on higher quality or design or frame building, but was based on marketing. And of course you could not build an oversize steel tube to compete, because it would be weight prohibitive. As a result, steel was out of business for years.

  • 1 |-10+11

    And now that steel has come back, there is renewed interest in the Logic tubing. It was so revolutionary and evolutionary, especially when it comes to its TIG-welding applications. With very few modifications, what we were doing back in the 1980s is completely applicable to the bikes we are designing today. Okay, there are some differences, say with sloping top tubes, the integrated head tube and the carbon front forks that are standard today. The whole front of the bike is very different. Those things were not there when the industry left steel. So, mostly, the Logic tubing simply has to be "tuned" to all of those new things that are going on today.

    It’s a challenge though. And my challenge is to do it intelligently. A traditional 1-inch fork for example, was softer and more compliant than a 1-1/8-inch. To make carbon safe it has to sacrifice some of its shock absorption to maintain its crash-test strength. Steel in a crash testing yields and bends, but it doesn’t break apart. Carbon fiber will fracture and nobody wants carbon-fiber shards sticking in their body. As a result the industry has had to produce super-stiff forks that have safe crash-test standards. They are not ideal in terms of handling but they are lighter and have become the standards of the day.

  • 1 |-10+11

    How do you see steel bikes evolving in years to come? Well, that’s a great question and one I think about. There’s been a lot of poor understandings. In order for steel to evolve, if it’s to go back to being the way it was, it has to incorporate the state of people’s minds today that have embraced carbon forks and other things. Certain things have devolved and need to be understood, while other things need to evolve and make room for the new things people want to use. But there have been improvements and the value of the pure ride-quality of steel is rebuilding in people’s minds.

    It’s a constant balancing act however. The head tube of today’s Logic for example is a forged head tube that incorporates the bearing for a superior ride. A lot of people have machined out a big tube thinking it looks cool. So there is a balancing act between a tube’s big diameter over its strength. It’s frustrating to say this, but there are very few engineers that build today. There are a lot of builders today that are into art and style. Paint jobs can cost more than bike construction these days.
    ---
    You also make high-end carbon bikes. How has your experience in steel affected your approach to carbon? Well, to start with, there has been a lot of misinformation in the marketplace today and the big companies have risen up and are using whatever marketing effort they can to defend their big tube sections on frames, basically their billboard space. They are going to tell you that it is more elastic, compliant or whatever.

    But they have already had to walk backwards. Look at the diameter of the seat posts. Today they’re back to the 27.2 size. In order for a carbon bike to match the weight of a beer can and not to break, it has to be super-stiff. If you have stiff rims and a stiff frame, the only way to gain elasticity is in the seat post. It’s the last place they can find some flex in the system and keep their billboards. They will talk about aerodynamics until the cows come home but, basically, bikes are less rideable to the average person. There is a cost and consequence to the emphasis on weight and aerodynamics.

    That is why, when you look at my carbon Break-Away frame, the obvious thing is that there are conventional diameter tubes. That is because the only way that you can get elasticity out of carbon and assure good ride quality is to go back to making it to a more similar diameter to steel tubes. The bending equation in diameter of the tube is the function of the square root of that tube. And the strength of that tube is a torsional-formula cube of that tube. These are all formulas that I learned and understood from my engineering friends back when I was a teenager working with steel. Tubes need to bend, to arch and bow, to absorb shock. Building bikes with more traditional-diameter tubes is the way you get that. So, my choice of tube diameters on my carbon bikes is a very clear reflection of the lessons I learned in my years working with steel.

    ne ne ne...ne razumeš kaj želim povedat...aerokolo že po osnovi ne more biti vsestransko...to je taka specifika od kolesa, da ne more biti vsestransko...recimo...vsestr ansko kolo je gravel bike...al pa mogoče kak endurance bike...to pa je to

    Aha. Mas prav. ;)
  • 1 |-10+11

    Enkrat sem naletel na dober komentar o gravel/endurance/adventure kolesih. Ali so res vsestranska?

    Sam razumem vsestransko kolo kot:
        - ima navadne zavore, saj jih je veliko lažje sam vzdrževati kot diske
        - ima žice speljane na okvirju
        - navadna krmilna opora
        - omogoča vsaj 32 mm široke plašče
        - ima nosilce za prtljažnik in blatnike
        - ima dva nosilca za bidone
        - ima vsaj kompakt, če ne triplo, ne pa samo en zobnik.

     

    Takšno kolo imaš lahko za potovanje, kot specialko, gravel kolo, ciklokros, ...
