KMC 9speed ebike specific chains

Post by 12-C » Aug 19 2017 3:45pm

So I'm in the market for a new 9 sp chain and it looks like KMC has 2 specific chains for this purpose.

the http://kmcchain.us/chain/x9e-turbo/and http://kmcchain.us/chain/x9eept-eco-proteq/

I'm wondering if anyone has any feedback regarding these chains or insight?

Hmmm, I'm surprised that there's nobody that has given this chain a try.

They don't list any tensile strength specs etc but seems like a tailored chain for the demands of ebikes.

Please chime in with any experience with these chains or any other ebike specific chain!

All i know is that they are way stronger than a regular bike chain from a department store. I broke two Walmart chain breakers trying to push one link pin out of a kmc 7 speed chain for ebikes, tried the bell brand chain from Walmart and pins push thru with ease...I need to order another heavy duty chain breaker i guess, i have a 219 cart chain one but its way different size. Snapped them clean in half even with lube.

These are on KMC europes site, but i`m sure they`re all available in the U.S.
