Lance won with oclv carbon. He never road TCT.singlespeed1 said:I have a 2005 Trek 5000, OCLV Carbon 120. The 2006 Trek 5000 has TCT Carbon. Could someone tell me the difference between Carbon 120 and the TCT Carbon. Is there a difference and if so which is better.
That's not a completely accurate statement. Giant TCR and Specialized S-Works are just as good as any Madone and they are made in Taiwan and China. Cost plays the biggest role here. If you look at a 2005 and older Trek 5000s, they had the same OCLV 120 frame as the higher level 5200,and 5500 models. the difference in the numbers had to do with the component groups:5000 had 105; 5200 had Ultegra and the 5500 had Dura Ace. Labor costs are higher on the OCLV (being that it's made in the US) so to keep the 5000 profitable, they switched outsourced to Asia to get the TCT carbon frame. It is a lower quality but not because it's made in Asia but because the level of carbon used. It's still a good frame or Trek wouldn't put their name on it. It was just a better alternative to axing the 5000 model. Remember, Trek's first full carbon-framed bike was the 1989 Trek 5000. It doesn't matter anymore since Trek changed all the names of their bikes anyway. What was the 5000 is essentially the Madone 4.7 today.WhiskeyNovember said:OCLV is the superior carbon. TCT is made overseas of rather generic carbon fiber, while OCLV carbon is sourced from the very people who provide carbon to Boeing, Raytheon, etc.
The process used to manufacture OCLV, however, is what truly sets it apart. Have you ever seen cheap window tinting on cars? Usually, there are many air bubbles between the tinting material and window. Most carbon frames have similar pockets of air (or "voids") scattered in between the many layers of carbon fiber cloth. These voids are weak spots, resulting in less strength, or requiring additional material.
OCLV uses a patented process that brings the level of voids down to 1% or less, if I remember correctly. To put that into perspective, the aerospace standard is up toward 4% or 5%.....so, technically, OCLV carbon is a bit more refined in that respect than the carbon fiber flying around at 600mph and 40,000 feet on $100 million jets.
In addition, OCLV frames are manufacturered in Waterloo, Wisconsin, making the workmanship and quality control superior to most frames manufacturered in China or Taiwan.
That's a funny bit there. Anybody can produce a sub-$2000 carbon frame, at the same quality as any $5,000-frame. A Madone 6.9 costs a couple hundred bucks to produce. And Trek doesn't compromise quality any more or less than pretty much any of the reputable frame manufacturers out there. Remember, this is about making money selling a product, and that's it. The prices you pay are what they are only because of advertising, and because people are willing to pay those prices.Richard said:Still, the competition to produce a sub $2000 full carbon is fierce, and I doubt Trek will compromise quality.
Do you have source information for that statement?Pirx said:That's a funny bit there. Anybody can produce a sub-$2000 carbon frame, at the same quality as any $5,000-frame.

That doesn't surprise me at all. Still to be competitive, Cannondale had to do it because everyone else is doing it. Trek did it with the TCT and they'll probably do it with the OCLV one day. For die hards, hopefully not soon.Richard said:Re-reading my original post, I should have said that the competition to build a $2000 full carbon "bicycle" with a decent component spec is fierce.
But consider this. When Dorel recently announced the end of American production for all Cannondale frames, their CEO was quoted in Bicycle Retailer that labor costs were 20 times higher in the U.S. than China. 20 times!
