My riding buddy bought a Trek 1000 last year - he is not one to spend a lot of money on his bike even though he is very affluent and could afford whatever he likes. Before starting a century last weekend he checked the bike into the free bike mechanic at the start because he could not get the brake release to go back to the riding position, the mechanic set it for him but said the caliper may need replacing (because now it won't open to get the wheel out), he went on to say that although the calipers on that bike looked like Shimano they were chinese knockoffs - closer inspection, they did not have a manufacturers label on them at all, but they did look like Shimano. I was shocked if this was true, first of all Trek is a reputable company and selling a road bike with Chinese knock off parts is low class. Looking at the Trek web site for thier low end roadies they say the brakes are alloy with Shimano levers - so I guess that's the clue. What a disappointment, I would have certainly only expect this with a Wally-Mart special.
Now on the positive note - he loves his bike, he rides well on it so I guess that is all that matters. He has put 1500 miles on it since last Sept so we will see how long the components hold up as he is a big (not fat- but tall) rider and can put out pretty good power. The bike does chuck the chain from time to time but that just may be an adjustment thing.
