Picked up the new Trek 2.3 yesterday and went for a 20 mile ride. It has a red and black paint scheme that looks really good (to my eyes at least) and preferable to the other Trek color schemes, excluding Madrone's. Much more nimble and fast than the touring bike I've been on for the last month. My ride loop is flat and straight so a review of performance in more demanding road conditions will have to wait.
Below is a link to Trek's website about this model, I'll post some real pics later.
My budget was to upgrade for about $750. The biggest decision was the wheelset, and, after much consideration I did Mavic Krysiums. The reviews of the wheelset are mixed in they are heavy, but, durable. At $260 It didn't break the bank. I'm reusing my 700x25 tires as they ride very flat free and add to comfort. I'll go to something smaller on the next set.
The Group came from an Epic transaction from Helluvaskier. Shimano 105 shifters and derailuers, Ultraga crankset and bottom bracket. He has my slightly used Hart skis, I now have his slightly used group. Thanks Greg! The group works as expected from this line, solid. A future upgrade will changing gearing to permit more comfortable climbing.
We selected Bontrager parts standard to the Trek line for the headset, seatpost and handelbars. Prior to the full buildout but with the wheels, headset and cranks installed, my LBS asked me to come in and select a handelbar that I felt comfortable with for size and drop configuration. We spent 3/4 of an hour changing out bars until I was comfortable. The shop fee for the entire build out was $120 and that included a final fitting session to fine tune the stem lenght, seat height and position. My total cost was $820 for the new components and I've got a bike that has a MSRP of $1800 and retails for whatever price you can negotiate.
In addition, I bought new Shimano SPD road shoes and road pedals. Good to go for many years! Ride on!
