Mercier experiance
I have had two Mercier Kilo TTs, virtually identical bought from the same woman on ebay . I have one now that I ride on short lunch rides, I like it. I had another one that I rode for awhile and then sold to a guy for more than I had paid for it. I went about 8 months and then felt I needed another. Each of my bikes had some modifications to suit me brakes, bars, stem, and pedals. These bikes are a great value. I don't ride that many miles on mine but, the guy I sold my first one to has put a ton of miles on it and had no problems.
I'm currently looking for a nice old Italian frame that I may move most of the parts over to, not that there is anything wrong with the Mercier, it just does not have the soul of a fine old Italian ride. The firt pic is my first Kilo TT the second is the current one. The diferent modifications I made are easy to spot, I really like the current one better with the single stealthy brake it just looks more clean. The difference between the 2005 and 2006 frames is slight but you can find it if you look close.
