Very good strong chain. It takes the abuse of a 1,500 watt motor while riding in the bushey woods where lots of things get caught in the chain. It's good quality and has minimal wear if properly maintained.

Good budget chain, but there's better budget chains out there. Even with wet lube, the chain showed premature rusting after only a few rides

This chain is expensive but the old saying is right you get what you pay for. This chain has a dlc coating that makes it extremely corrosion resistant and pretty much self lubricating. There's a reason they coat gun parts with the same material. It's extremely durable.

We shall see if it can last on my 1000 watt e-bike. As for the quality, it's good. The master link is matching color, which is nice but it was quite hard to get together. I'm sure it's not going to fall apart though. Hopefully it can take the torque of my 1000 watt motor

My son snapped his chain on his MTB - this is a perfect fit with his Box3 drivetrain. This chain works on Box2 or Box3.
