The Scott Addict RC 20 Ultegra Di2 Road Bike is built around a single obsession: weight savings that translate directly into speed on climbs. The HMX carbon frame sheds 300 grams over its predecessor through a PP mandrel manufacturing process that molds inner surfaces with high precision, eliminating the reinforcements and filler material that add mass without adding stiffness. What Our Gearhead(R) Experts Are Saying:"The 300-gram reduction in frame-kit weight over the previous generation is the number that matters on a long climb. The bike accelerates out of corners and over rollers without the drag of the old version."Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearhead(R) Experts are always here to help.
