Dedhed thank you for the links and Lee for the bike suggestion, that Sulry CC does look really nice.

So basically it comes down to manufacturers. My current trek has the Shimano atlus that has worked fine for the 2 years iv'e had the bike. But for the road bike I would probably step up into the Shimano 105 (level 3) area. I noticed the SRAM Rival is similarly priced I may check into those also, they seem to be a lot lighter also for some reason. Thank you, now I at least know the quality level of some of these parts so I can get started and shopping around used and what not.
