Generally a fan. I've got two and did have a third.
My Pro Carbon is a great bike to ride and is a relatively rare silver one with green decals which I think looks great - I've told this tale before but when I was wheeling it out of
Halfords I was stopped and asked where I'd bought it. The person asking refused to believe that Halfords could sell such a bike!
But - when I was looking to replace the Road Comp, with it's fantastic mercury silver / grey paint finish, the equivalent model was in metallic red.
As a colour it looked far better in the flesh than on the website but the paint finish wasn't great on the one in the shop. In fact it was distinctly "orange peely" in places. And the fork was a noticeably different shade to the frame - I suspect they'd been painted at different times, possibly in different places, and certainly with different batches of paint.
Regardless, it put me right off and that's when I bought the Giant.
I've got to say that I don't find many of the current range particularly inspiring. Not a fan of the current colour schemes / decals either and while they're still competitively priced I don't think that they're the bargains they once were. Sorry.
