105 component group is far superior to the RSX that was on my old bike. Comfortable and fairly light, Rolf wheels stay true for many many miles. Had my sights set on titanium, but the cost is simply ridiculous. This is all the road bike I am ever going to need. The right shifter does rattles a bit, put some tape on it.
Bottom line is it is a great bike.
Great fit, solid wheels, excellent components, looks great too. I am looking forward to putting a lot of miles on this bike. Relaxed seat angle requires adjustment in bike sizing from what you may be used to riding. Paint chips easily. Shimano 105 shifting levers tend to rattle on bumpy roads.
