SRAM

X-Sync EX1 Sprocket Chainring for Bosch Motors

The EX1 drive train was designed specifically for the demands of electric-assist mountain bikes: a wide gear range with bigger jumps between gears and sturdy components to handle higher torque loads. Liberal use of features found on SRAMs high end MTB parts provide high value, quiet operation and ease of service.

• Compatible with Bosch mid-drive E-bike systems
• X-Sync (wide-narrow) tooth profiles for great chain management
• Ideally mated to E-Bike Specific 10-11-12 Speed Chains for extra wear resistance
