The only differences I can see between the 2009 model and the 2010 model from the Trek website is the front derailleur and saddle. The 2009 model has a Shimano C102 front derailleur. The 2010 model has a Shimano M191. A quick look on the internet shows the C102 cost more. In this case the 2009 model is the better deal at the same price. The 2009 model has a Bontrager Nebula saddle. The 2010 model has a Bontrager H1 saddle. I could not find a quick reference on the price difference between the two saddles.
