I have narrowed it down to these three in the 2010 models. I realize the geometry is different in each bike with the specialized the most comfortable and the trek at the opposite end of the scale. Both the Trek and the specialized come in at the same price with the Giant costing about $200 less. The Giant gets good reviews but it's hard to really find out the quality of a lot of their components since they are in house and makes me wonder if I would be able to swap them out later for upgrades if i desire to do so. So all things being equal I would appreciate any feed back regarding which bike any of you would lean towards. I haven't ridden any but plan to this week. I'm just wondering if any of the three models stand out above the other?
