The design is virtually identical to the Shimano Ultegra R8020 groupset and the Shimano Dura Ace R91020 groupset. The complete drivetrain has received an upgrade. The Shimano 105 R7020 Disc groupset has a revamped crankset, rear and front derailleur and shifter set. The crankset is wider and more rigid to improve power transfer. The rear derailleur is now equipped with Shadow technology, which means the derailleur is fitted below the cassette and prevents external impacts. The front derailleur has a cable tensioner and a new, more compact design that opens up new cable routing options. The shifters are more ergonomic and compact, which results in them sticking out less on the handlebar.
