Yearning for long days on the road, Bianchi's Impulso S-Sport Tiagra will leave you happily exhausted and eager for more. The lightweight frame sports an endurance-oriented geometry for hours of comfort and fun, and the triple hydroformed aluminum tubes provides stiff, precise handling. Plus, with Bianchi's Kevlar inserts, the carbon fork provides an ultra-smooth ride. The lightweight Reparto Corse wheels accelerate and climb with ease and the crisp-shifting Shimano Tiagra 10-speed drivetrain provides the perfect gearing for sailing over mountains and flying down open roads. Shimano brakes offer easy control right under your hands. You'll also love the sturdy Reparto Corse stem, bars, and seatpost, not to mention the plush Selle San Marco seat.
