E-BLOCK™ shifting technology is a fundamental redevelopment of external drivetrain shifting. On the E-BLOCK™ cassette, the chain has a defined link position on each cog. Cog architecture has been engineered to work with both inner and outer links of the chain, which allows extremely refined shifting for both inboard and outboard shifts. The result is precise and robust shifting performance in any situation, even with full motor support.
