Well it's been three year since I've bought the Mercier WT from Bike Direct. Save up to 60% off new Mercier Singlespeed Track Bikes - Kilo WT - Save Up To 60% Off Brand new Bicycles I love it!! Great bike but some things should be change when the bike is new. Seat and tires are cheap and heavy. This maybe be true in most bikes in this price range. Other than that nothing else I replaced. The bike now has over 7K+on it and runs great.
