Argon 18 Sum Pro Shimano Ultegra Di2 Road Bike: Specs, Price, colors & Features

The Argon 18 Sum Pro Shimano Ultegra Di2 Road Bike carries the Shimano Ultegra CN-M8100 12-speed chain, giving it smooth, quick transitions across the cassette. Shifting is handled by the Di2 R8170 shifters, known for electronic accuracy in demanding conditions. The frame feels quick on the climbs and settles well on descents. It responds confidently during sudden sprints or sustained efforts on rolling terrain. This setup works well for those seeking subtle electronic control without mechanical interference.
