Need advise on Giant
I'm currently riding a mountainbike on slick and thinking to get a roadbike once and for all. I've done my research and short list to 2 bikes
1. 2004 Giant TCR2 complete bike (yellow color, thinner fork) but upgrade to Ultegra group, xero XR1 wheelset etc or
2.2003 Giant Team TCR frame (custom built ONCE, hugh flat aero fork, black color)) with ultegra, Xero XR1 wheelset etc
They both cost the same, the thing is I'm not sure if the Team frame would be better than the built up bikes has to offer. Are there any different between the 2 in terms of performance or only graphic/color?
2nd Ques is there a lot of difference between 105 and Ultegra? Any input would be appreciated cos this is the first time I'm getting a roadbike and I wouldn't want to be stuck with something I couln't sell later. Most of my riding currently on my mountainbike is hilly terrain ride would last around 4 hrs over 90Km
