The fork is all carbon, with a 1 1/8" integrated headset.
It has Shimano Ultegra brakes, Derailers, Brifters and Cassette, Truvativ Elita two-piece crankset with external bearings.
The wheels are no-name hubs, with Alex AT-400 rims, 28 spokes front and rear. The Alex rims look very similar to my favorite Mavic rim, the Open Pro. 28 spokes is a fair compromise between traditional 32/36 spoke wheels and the currently trendy boutique wheels with far fewer spokes. I'm afraid that the current trend in road bikes is to treat the wheels as "disposable/consumable" parts like tires and brake pads.
Anyway, so far the wheels are holding up fine under my 235 pounds.
