Bosch Gen 4 ChainringThe Bosch Gen 4 chainring was created taking lessons learned from developing Bosch's SL chainrings. They created a similarly minimal aesthetic but adapted it to be stronger and work with the Bosch CX Gen 4 motors. While being lightweight and beautiful, the 7050 aluminum provides sufficient durability for eBike use, and the new M3 narrow wide tooth profile reduces noise and increases drivetrain durability. Compatible with all 11 and 12 speed drivetrain
