The 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 systems, regardless of brand, or level of the chain.
• Quieter, Longer-Lasting M3 Profile • Direct Mount • 34T, 36T, 38T Options • Boost Chainline (53mm) • Designed for Bosch CX Gen 4 ebike motors

Q: Can this 38th chainring be used on a 2021Moustache Samedi tandem that comes with an FSA 34 tooth chainring? Not sure about the tandem aspect with the timing chainring next to the drive chainring and the possible differences in driveline offset?

A: Hello, No it is not possible to change the chainring size on the tandem as the front and rear chainrings must be the same size to keep the two sets of pedals synchronized.

A: I was told that you can have to up to 2 teeth less than the original chairing. Can not add on teeth from the original that came with the motor
