E*THIRTEEN chainring e*spec Direct Mount Bosch SX / CX Gen4 | 2023
The e*spec Direct Mount chainring for Bosch SX/CX Gen4 e-bike drives.
The "spokes" have been shortened slightly and made wider, thus significantly stiffening the entire chainring. A revised narrow M3 tooth profile eliminates chain noise and reduces wear on the entire system. With the proven alternating thick-thin tooth profile, the chain is always held securely in place.
The chainrings are available with 34 or 36 teeth.
