yes on all points, frame sizing will depend on intended use in many cases. i opened a can of worms here haha, as for the comment about over wieght vs carbon... we get alot of folks looking for super light carbon bikes,, and theres options of running 105 gear or durace,, why go the extra 300 bucks for a few grams.. and go ride a day and loose a pound haha, but hey nothing works like top end stuff, and once you get used to it,, youll never go back heheh. on this subject everyone in the sport will see things slightly differnt , i know my product and how we fit bikes.. i just learned the stuff from the guys running the biz for 30 years heheh.. anywho lets get this thread back on the picture talk enuff techno bike geek stuff
