This three peice kit allows you to either upgrade existing eTap drivetrains or creates a base to add other eTap components to build a drivetrain upon. Included are a SRAM eTap WiFli rear derailleur, 11-32T Powerdome cassette and SRAM Red 22 11 speed chain.

Expanding your gear range has proven to be a real growth area for many riders. The wider and lower gear options represents a more realistic gear inch turn, resulting in improved performance. The rear derailleur is slightly lengthened to accept the larger gears, but not impede performance.
