Bianchi Impulso S-Sport Tiagra We wanted a suburban speed machine. Fast enough to join in on a spirited shop ride yet practical and comfortable enough to make weekend coffee shop run with the kids. A flat handlebar version of our best selling aluminum road bike the Impulso, gave us just that! All the technology features and benefits of the Impulso have carried through to the S-Sport version. The single chain ring crank makes shifting easy for riders while disc brakes provide powerful braking in all types of weather conditions. The Impulso S-Sport utilizes our proven K-VID (Kevlar Vibration Isolation Device) vibration damping technology in its full carbon fork, UTSS (Ultra Thin Seat Stays), THT (Triple Hydroformed Technology), as well as BAT (Bianchi Active Technology) to optimize the rider’s sitting and pedaling position on the bike. The Impulso S-Sport tubing profile has been maximized to provide best in class rider comfort for an aluminum frame while providing steadfast acceleration from the over sized downtube and chainstays. The Impulso’s THT (triple hydroformed technology) top and aero head tube allows for stable, stiff and responsive turn-in when cornering switchback roads. THT allow us to make an aluminum frame that exceeds European CE breakage standards; 6 times that of the minimum requirement. The sculpted, UTSS rear portion of the bike reduces the amount of vibration that comes up into the rider’s seat.
