Cycling in Waterloo Region

Thanks for the feedback - my setup is a bit unusual I guess, as for the 2nd bike it has a Shimano STePS Middrive, so I need a really strong 10-Speed chain (for the width). At 118 links, the existing chain has the derailleur jockey wheels very far forward - a little too far for my liking. 116 would be impossible (I checked). I’d actually prefer to lengthen it to 120 links to have the derailleur a little more relaxed.

Ah okay, sounds like you need one of the e-bike specific chains that KMC makes, like the KMC X10e EPT with 136 links. I dunno if KMC distributes them in Canada or not... I've ordered from bike24 in the past but the 20 euro flat-rate shipping is hard to swallow for ordering just one chain. I've also been dinged the exorbitant "brokerage" BS that DHL will pull. I'm a big fan of KMC chains and have never had an issue with

Cassettes can wear out from running a worn chain for too long but catching it at 0.8 likely saved you that trouble, but it'll usually slow up as slippage when you're in a low gear standing up... I don't have any experience riding an e-bike so I don't know if they would make it worse or better.
