hd chain perfect for e dirt bikes;

Verymuch enjoyed both stainless chains but third time getting the BMX chain this is all that was available but this is the wrong spacing for BMX. Not to be confused with the discontinued BMX. Got Skyway Mag wheel set now I am building a single speed bike around them because I love them so much not with this chain but clearly this is a much better built chain than the previous model please release this in BMX spacing this won't work with BMX.;

Great pains I use them on my e-bike they work very well;

I have had to replace multiple chains periodically for my mid-drive ebike since the motor (1000W) is really tough on them. This is the first chain that has so far outlasted all of them and at last check it was still not registering any stretch. I'd recommend you clean the new chain with solvent and grease it properly since it comes with a waxy coating which would be a dirt magnet. Price was also reasonable.;

Have a few of these chains. Easy to install master link provided and will outlast your chainrings/cassette before stretching if you are not an extreme crosschainer. You get wide links and lots of links... great if you run a triple chainring. Fits my 48x36 drivetrain which was a few links short for a sram chain. Managed 4000 miles on my first KMC chain on a 2 chainring setup and only replaced it because the cassette teeth wore out and started skipping. Old chain still worked on new drivetrain though it had some slight side play. Saved it as a backup.

Factory lube is a bit sticky wipe it down after the first few rides or remove it all and swap to dry lube.;
