Steel direct mount chainring - suitable for e*thirteen espec & Bosch CX Gen4

ethirteen espec Direct Mount Chainring – Steel (Bosch SX / CX Gen4)

Maximum durability for powerful e-bike drives: This ethirteen espec direct mount chainring was specially designed for the extreme requirements of the Bosch SX and CX Generation 4 engines developed. Using high-strength steel and an optimized construction, this chainring is the first choice for riders who don't want to compromise on durability.

Optimized rigidity & smooth running

Compared to standard chainrings, the “spokes” on this version have been shortened and made wider. The result is a significantly stiffer chainring that transmits the high torques of modern drives without torsion.

• M3 tooth profile: The revised, narrow tooth profile effectively minimizes chain noise and reduces wear on the entire drive train.
• Narrow-Wide Technology: The proven, alternately thick and thin tooth profile ensures outstanding chain guidance and keeps the chain securely in place even on rough terrain.
