Haven't lost a chain yet

I converted my old Cannondale to an ebike using a TSDZ2. On the first ride using the original Shimano XT 9-speed, I dropped the chain on a bumpy downhill section. I upgrade to the Box 8-speed with this chainring and haven't lost a chain since. Its very robust and I can shift under power even with the motor putting out about 750W.

Good addition to the 8speed drivetrain but you can't use the master link

Inexpensive. Holds your chain snuggly when running a clutch derailleur, I am running the Box 8speed. Overall I am definitely pleased with the 8 speed and this narrow wide chain ring. My one complaint is that I can't use the 8speed master link when using this chainring. The master link is not compatible due to the link width being to narrow.
