Okay, so I'm looking to upgrade from my 1993 Trek 2100. My budget is about 1500, but I can push to a little more for the "perfect" bike. What are thoughts regarding the Cannondale CAAD9 4 vs. Trek 2.3?? Is it worth it to go for the SRAM components on the Cannondale? (Are SRAM components better than the 105's on the Trek?) Or, if anyone knows of a better bike in the 1500-1800 range that I'm not aware of, by all means let me know! Thanks in advance.
