Technologies:

Exact Actuation
Sram, in creating the gear shifting technology for road groupsets from scratch, has applied the 1:1 technology fully known from MTB bikes (the movement of the lever on the handlebar corresponds directly to the movement of the derailleur carriage). Exact actuation helps stabilize the rear derailleur's carriage in the daunting task of balancing its operation, under conditions of narrow cassette lace alignment, with the need to maintain equal tension on the cable in the armor. As a result, an indexing system with the most friendly adjustment has been achieved, whose operating conditions never deteriorate.

Direct Route
The design of a rear derailleur and the associated method of routing the cable to the derailleur. In this system, the cable runs through an arm protruding from the rear of the derailleur, so that the armor running to the derailleur is straight rather than arched. This makes the derailleur less prone to fouling the last section of the armor. Di.R.T. was introduced to the bicycle world in 1996 by the German company Sachs acquired a year later by the American company SRAM, which uses the system in its current derailleurs.

Cage Lock
Cage Lock used in the design of the rear derailleur, makes mounting/dismounting the rear wheel or changing the chain faster and completely hassle-free. The derailleur is locked by pushing it forward and locking it in that position.

Roller Bearing Clutch
Derailleurs made with the help of Roller Bearing Clutch tehnology, provide maximum drive stability in the most aggressive terrain. Unwanted rippling and lateral movement of the derailleur and chain are eliminated without affecting the precision of the gears.
