So, people, please give a sugestion for a good chain for my ebike. I have a Sram SX 12 speeds transmision on my Scott ebike and i want to buy a new chain. But i don't want to cost me a fortune and also i don't want to change it after 500km. I heard about Connex, Sram and KMC chains but i need something good for my needs. Please give me an advice from your experiences. Thank you !
