The fenix replaced one of my favorite all around'er bikes of all time, the excaliber which I was sad to see go. I have to say that I am very very happy with the Fenix SL. The weight is not bad at all with the ultegra set up and feels very lively. The bottom bracket is nice and stiff giving you plenty when you stand on it. It's a bike you won't soon out grown, The ride is good but I would say down the road you might do a carbon post and bars to really make it sweet. I've owned every Ridley model out there now and never been disappointed and the new Fenix SL has been no exception. They size pretty big, at 5'7" I ride an XS which came with a 90 stem and offset seatpost. Feel free to contact me directly with any questions on sizing, the frame, or components.
