SRAM EX1 Rear Derailleur 8-speed black

The EX1 rear derailleur uses the robust design and precise shifting characteristics of the X-HORIZON design to create the world's first rear derailleur specially developed for E-MTBs. The EX1 rear derailleur is designed for high torque and low cadence shifting in an 11-48 tooth E-BLOCK cassette. This allows the rider to shift cleanly and reliably at all times so that he can concentrate better on his ride.

CAGE LOCK
Thanks to the CAGE LOCK technology in the rear derailleur, disassembly and installation of the rear wheel and chain assembly are faster and easier than ever. Simply push the cage forward (to release the chain tension) and lock.

ROLLER BEARING CLUTCH
ROLLER BEARING CLUTCH derailleurs offer maximum drive stability - even on murderous and highly demanding terrain. The ROLLER BEARING CLUTCH technology puts an end to shaky rear derailleurs and beating chains - without sacrificing precision.

X-ACTUATION
The X-ACTUATION technology specially developed for SRAM 1x ensures precise and constant shifting operations along the entire cassette.

X-HORIZON
The parallelogram design of the X-HORIZON rear derailleur limits movement along the horizontal axis, thus eliminating the so-called "ghost-shifting" and simultaneously reducing the shifting force. For faster and more precise shifting, the large offset of the upper pulley ensures a constant chain distance in each gear.

X-SYNC
X-SYNC 1X chainrings from SRAM ensure maximum performance and durability. The long SRAM X-SYNC tooth edges grip the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile as well as the rounded inclined edges support the chain guide. To provide the best possible performance even on muddy terrain, the X-SYNC chainrings have recesses for removing dirt and mud from the inner chain links and rollers. The X-SYNC chainrings manufactured in Germany are an important part of the 1X drive from SRAM.
