2015 Trek Domane 4.3 Disc

Trek's Domane 4.3 Disc offers unmatched ride quality, comfort and quickness. This full carbon road machine is graced with race-winning Trek technology like IsoSpeed and an endurance geometry to make it a true ride-all-day rocket. It masters long, epic rides with ease while delivering unrivaled speed and bump compliance. The 4.3 rolls on a precision-shifting Shimano 105 drivetrain with compact cranks for easier climbing. Through axles front and rear give you serious corner-carving ability, and the hydraulic discs deliver impressive stopping power. Plus, you get quality Bontrager components including aluminum wheels, bar and stem, and a carbon post. Uncompromisingly fast, confidently stable, sublimely comfortable, the Domane 4.3 Disc has it all!

I've had my bike for less than a week,(1st road bike in 30 Years) and have truly enjoyed the ride. The bike makes the rough roads a breeze to ride. It is my second Carbon Fiber bike(other is a MTB). Love the STI shifters, and the Disk Brakes grab and stop the bike quickly and affectivly. Looking foward to a lot more riding.
