E-thirteen E-Bike DM Bosch CX Chainring

Our new direct mount e*spec chainrings use our new M3 narrow-wide tooth profile, which reduces weight without sacrificing chain-retention. In making our SL and UL chainrings lighter and more beautiful than their predecessors, we adapted a similar design to work with Bosch, Brose, Fazua and Shimano motor configurations.
