Another Ruby gal here. I have the Expert and it really is a great ride. DH has the Tarmac and loves it as well. I did upgrade the front chainrings and crankset to Ultegra. The year that I bought came with FSA 50, 39, 30 and I wanted a 52, 39, 30. Now it looks like they come with the the Ultegra SL 52, 39, 30.
