I didn't know about the peeling problem and I've not had that issue with my 10 speed chains. What I'm looking for is better materials, longer wearing materials, and frankly a wider pin and roller assembly to spread wear over a greater surface area. 7 speed chain is wider that 10 speed chain and this width is in pin and roller length, both of which are the wear areas of a chain. I was glad to see the recommendations for tougher chain and will seek it out for my 10 speeds. No chains last forever but my e-bike 7 speed chain has been bulletproof with little signs of wear over 3000+ miles. I ride in Pedal Assist mode 1 and pedal all the time. I try to maintain a 12 to 15mph speed. Pedal Assist mode 1 on my RAD is 50 watts of power so you have to add some watts of your own to maintain higher speeds.
