SRAM EX1 electric bike derailleur 1x8 Type 3.0 | X-Horizon
Who wants to move its e-bike terrain sporty, brings its powertrain to its limits. Unclean shifts to load switching and cracks in the chain can be the result. The engineers SRAM have addressed these problems and brought to the market with the EX1 a switch group specifically for the requirements of e-bikes. With a Wide Range cassette with only 8 courses you can the extra power of the motor assist during acceleration perfect use, without having to turn too many gears. Equipped with the proven 1-up technologies of SRAM You can switch under load, without fear of chain bombings or material damage the gears intuitively.
The EX1 derailleur builds on proven SRAM X-Horizon Design. This special Schaltwerksparallelogramm limits the movements of the switching mechanism on the horizontal axis and reduces ghost Shifting to a minimum, with higher switching power. Was optimized the EX1 derailleur for use with the EX1 E-Block 11-48 cassette. This combination also E-Bike succeed typical switching with high torque and low cadence problem. The X-Sync jockey wheels engage with their optimized Narrow Wide tooth profile perfectly with the EX1 chain and prevent in conjunction with the Type 3.0 vibration damping jumping off the chain. The tensioner is designed extra large with 14 teeth, which makes for a quieter and more resistant poorer run of the chain. For ease rear expanding the EX1 derailleur has a Cage Lock, with which the derailleur cage can relax.
