I just got my Trek Carbon District it was born on 12/29/2009 built last week. I removed the stock bars and installed carbon riser bars and Paul levers, the bars were cut down 3 inches on each side. I live in Chicago and ride in traffic a lot and shorter bars help a lot for urban riding and getting through traffic. The bike stock out of the box is about 15 pounds in the 54 cm size.
The bike is super nice to ride, very smooth, the belt drive is very quite, rear wheel is super easy to remove and install to change the rear tire. Only learning curve is getting the belt on and aligned/tensioned correctly – read manufactures notes for installing and alignment…if installed wrong ie: not aligned you can throw the belt which makes this really odd rubber band sound “BOUNG” but the belt does not get thrown into the wheel or spokes - I’m happy to say…that really was the only learning curve and now it’s set and things are perfect.
It’s a really nice bike! My first Trek, carbon and belt drive…I ride a brakeless fixed gear most of the time – I’m 36 and have been riding brakeless in Chicago for 16 years…the belt drive is a really nice break from pedaling 24-7.
