The Aggraziato starts with a light and responsive frame you will find on our highest level carbon bike. The TRS monocoque frame and carbon fork with aluminum steer have been engineered to handle quick, float up mountains and carve down the other side. The Ultegra shifters are paired with the Shimano Ultegra rear derailleur and Shimano Ultegra front derailleur. The Shimano Ultegra STI controls allow for sure handed shifting and braking without removing your hands from the handlebars. The TRS Tommaso saddle has more padding on the saddle's pressure points to aid with comfort. The racy-sleek saddle is finished in a custom silver color that matched the handlebar wrap perfectly. The FSA Gossamer compact crank with external bottom bracket bearings is ideal for cyclist looking to get to the next level. The 50/34 chainring combination on the crank is a slightly smaller gear for those of us that aren't racing the Tour de France this year. It enables the user to climb with less stress on the knees and joints while cruising quickly along the flats and descents. The compact crank makes for less complex shifting than a triple and is lighter. Specifications Frame: Compact Carbon with Integrated Headtube.
