The Advanced 2 is constructed with T 700 carbon which is woven in house by Giant. It has the overdrive headset which is 1 1/8-inch top and 1 1/4-inch bottom bearings. (The Advanced pro and SL have the overdrive 2 with 1 1/4 inch top and 1 1/2-inch bottom bearings) Even on the roughest dirt roads the front end stays stable and tracks accurately. The D - Fuse seat post is amazing along with the frame for providing plenty of flex over the nastiest terrain, it's amazing how they engineered the carbon for the effect, no gimmicks here just state of the art carbon engineering. I've actually had to move my saddle forward half a centimeter to compensate for the compliancy or flex in the seat post. Also, the Defy did win the crazy cobble stoned Paris-Roubaix event in 2015.
For an endurance type frame the bike climbs well on regular roads and sprints pretty well too. It doesn’t climb or sprint quite as efficiently as my 2016 TCR Advanced SL but I'm comparing it to the TCR which is among the best climbing and sprinting rigs around. Wheelset is the Giant PR-2 Disc which are on the heavy side but after some really rough thrashings have held up well and are still true. Brakes are TRP Spyre-C, mechanical disc, 160mm rotors and work impressively for mechanical discs. Giant tires P-SL 1, 700x25, front and rear specific, surprisingly after hammering these over endless sharp rocks they've held up nicely, not even showing any small cuts as of yet. Drivetrain is full Shimano 105 except for the crank which is the Shimano RS500 and the KMC chain. It's just my personal observation that KMC chains are a bit more durable than Shimano but I feel are noisy in comparison. Front gearing is compact 34/50, rear cassette is 11x32 and with the climbs around this part of the country the 32 is sometimes very welcome. Bottom bracket is the Shimano press fit which I do prefer. Overall for endurance type geometry this bike does everything pretty well but really excels where it was designed to - on the nastiest of roads.
