Pinarello wants to make getting on a carbon-fiber disc-brake equipped bike easy. That's why they devised the Mercurio T2 Hydro bike.
The Mercurio is an evolution of the now-departed Treviso. The relatively slack seat and head angles yield a comfortable, stable ride, with a head tube height that is not as low as a WorldTour racer might want, but still allows you to get as low as you like. The dimensions make it more of an endurance bike, but with the rotor disc brakes, they were able to both make the seat stays better at damping vibrations and improve clearance for bigger tires and better mud clearance. It might not excel at a muddy cross race, but rough, gravel, and dirt roads it eats for breakfast. The frame, with right-sized carbon-fiber tubes comprised of 24HMUD plies, is designed to smooth out rough roads and keep you happily insulated from the vibrations that can drain the joy out of riding.
To help keep the costs contained, Pinarello has built up the bits with a large helping of Shimano Sora components. Sora comprises the crank, the STI shifters, the derailleurs, and cassette. Gearing is a traditional 50/34 compact up front that spins on an Italian-threaded Shimano bottom bracket and a Shimano 105 12-25 nine-speed cassette in the rear.
Likewise, they were able to specify disc brakes thanks to the use of Shimano mechanical disc brake calipers. The stoppers contain Shimano 160mm rotors attached to Shimano-hubbed wheels. Quick-releases secure the wheels in the frame.
The bike is also prepared for when you're ready to upgrade. The cable runs are Pinarello's Think2 system, meaning they can be swapped from mechanical to electronic, and back. Likewise, the mechanical disc brakes can be swapped for hydraulic and back. The seat post is a standard 31.6mm diameter and the stem clamps to a tapered 1 1/8" to 1 1/4" steerer, so stems are easy to find as well.
