i've been riding a Windsor Fens for the past 2000 miles and i'm completely happy with it. the only thing i did was change the saddle to the Forte Pro SLX for a measly 40 bucks. it has 105 brifters, cassette, and derailleurs and I've had no problems with any part of it. Eventually i want to upgrade to a nicer double crank, nicer wheels and maybe repaint it just for vanity. for the $740 i've spent on the bike, i couldn't be happier and couldn't have found anything NEW that would've been as good of a value. This was the first bike i've ever worked on and using the park tools website for reference i was able to get it riding perfectly. If you know what size you need and what you want from the bike dont hesitate to buy from BD
