Chain Stuff...

Okay, so I'm ordering a Park Tools chain wear measuring tool. And wondering what my choices are for a new chain (I want to be ready and change it before the gears need to be changed). I have close to 600 km on my bike so far.

What specifically is different between a "regular" high end chain and one specifically for e-bikes? My bike came with a KMC e.10 Sport chain. Is that my only (or best) option for a replacement?

In the past, with acoustic bikes, I've always used chains with regular links (where you need a tool to push a pin partially out to break the chain or to reinsert it). Can you use something like the SRAM Powerlock 10-Speed Chain Connector on an e-bike chain?

I've never broken a chain while riding and when worn, have always replaced them. Should I also buy some extra links and maybe pins to carry with me? I understand that e-bikes put a lot more stress on chains and problems are more common.

I found that KMC makes a "Missing Link Chain Connector" for their e-bike chains. How do you open/close it? With a regular chain breaking tool by pushing out a pin?
Slide the two parts of the missing link past each other so that the pin from each half falls into the holes. Then pull hard from both sides. The pins then snap in. To remove the link, use a pair of special plyers.

I bought some KMC stainless steel chain last time I ordered from modernbike.com I leave my bike out in the rain a lot when shopping or working @ my volunteer job. Probably not a lot of brass aluminum or zinc from scrap in a stainless steel alloy. Are a lot of those in "steel" from a certain infamous country.

Your reply has confused me a bit... the first part seems to describe how to open that missing link, but you finish by saying to remove the link you use special pliers. Oh! I think I get it!! The first part is describing how to secure the link, right? (Sorry, I'm feeling a little slow catching on today.) And what kind of special pliers? Not a regular chain breaking tool?

Yup, you got it. It’s to secure the link. To disassemble (it breaks in 2 parts) you can either use a pair of plyers or do it by hand. You will need the chain breaking tool to make the length correct. If you need 120 links but bought 134, you’ll break at 118 and add the missing link.

I would suggest that you look if your bike has a missing link. If you look at the part, you’ll probably understand how it works.
