Sram Ex1 Rear Derailleur Black 8s / Max 48t

The Sram EX1 Rear Derailleur is compatible with 48 teeth and 8 speeds and has been created exclusively for mountain biking since it offers smooth and safe shifting and a bearing clutch that eliminates chain bounce and bumps.This bike rear derailleur is made of aluminum, while the pulley bearings are made of steel. The X SYNC technology provides good performance, simple shifting, and silent operation. The X HORIZON allows for faster and effortless shifting, even on the most rugged terrains of the mountains. The EX1 derailleur capitalizes on the robust build and precise shifting attributes of the X-HORIZON® design, to create the world®s first derailleur specifically made for E-MTBs.Engineered to handle high-torque, low-cadence shifting across the 11-48 tooth E-BLOCK® cassette, the EX1 derailleur gives E-MTB riders clean, confident shifts, so they can spend more time enjoying the ride.Features:- Proven SRAM X-HORIZON® design that reduces shift force, ghost shifting and chain slap- 12-tooth X-SYNC® pulley wheels- The EX1 derailleur is purpose built for E-MTBSpecifications:- Speeds:8- Weight:289g- Outer Cage:Aluminum- Inner Cage:Aluminum- Bearings:Steel- Max Tooth:48- Pull:X-ACTUATION®Technology:CAGE LOCK®:- With CAGE LOCK® technology in the rear derailleur, wheel removal and installation®as well as chain installation®becomes faster and simpler.Just pushing the cage forward to create slack and lock it into place.ROLLER BEARING CLUTCH®:- ROLLER BEARING CLUTCH® rear derailleurs deliver maximum drivetrain stability®even through the most punishing terrain.With ROLLER BEARING CLUTCH® technology, derailleur bounce and chain slap are eliminated without sacrificing precision.X-ACTUATION®:- Developed specifically for SRAM 1x®, X-ACTUATION® keeps shifting sharp and consistent across the entire cassette.X-HORIZON®:- The X-HORIZON® rear derailleur®s ®straight parallelogram® design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force.For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.X-SYNC®:- SRAM X-SYNC® 1x chain rings provide the highest level of performance and durability.The SRAM X-SYNC® tall square teeth edges engage the chain earlier than traditional triangle shaped teeth.The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain.To provide the best possible performance in muddy conditions, the X-SYNC® chain rings have been designed with mud-clearing recesses for the inner chain links and rollers.Engineered in Germany, X-SYNC® rings are an integral part of the SRAM 1x® drivetrain.For 2x10V systems.- Compatible with cassettes 11-42T.
