SRAM EX1 electric bike cassette 8-E-block XG-899 11-48 teeth
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 heart of the EX1 group, the XG-899 8-speed cassette. Your E-block technology is a fundamental innovation for derailleurs. Similar to Narrow Wide teeth at chainrings, the chain has on the pinions of the cassette a fixed position, and works with either the inner or outer plates of the chain. That allows, despite the large ratio steps of the Wide Range cassette optimal switching capacity in both directions at high torques. With 11-48 teeth, the cassette has a translation range of 436%, so you are prepared for the steepest ramps. The production of hardened tool steel ensures low wear and thereby a very long shelf life.
