Opus's Vivace 2 means business with it's high-modulus carbon frame and fork. A wide bottom bracket gives you stiffness for those snappy accelerations we all love, while super-slim seatstays offer up just the right amount of compliance for all-day comfort. Shimano 105 is the group of choice, with 22 speeds to choose from, not to mention smooth shifting and the wonderful ergonomics that Shimano is known for. Notice that internal cable routing? It keeps things looking nice and neat. You'll roll on Mavic wheels and tires that work harmoniously to deliver sublime ride quality. And, a carbon post teams with an aluminum bar and stem to round it out.
