Checking the wear of the chain

[JackStraw]

Hi All,
Has anyone used this tool to check the wear on the chain?

From tool to tool it is different. From the video I have seen the Parktool's tool I should not insert into outer links but this tool won't fit into those.
From what I can see now the left bit is to go first (not second as I thought initially).
Right side bit drops into the chain link at 0.75% which tells me this is worn already.
I applied pressure on the pedal to stretch the chain.
Is it expected for the chain to wore down in like 8 months (KMC X8)? I replaced to a new chain and cassette at the same time.
I think I did like 600 miles on it but not sure.
This is an ebike so wonder if the assistance contributes to the wear but I am not a hefty chap nor I ride in Sport/Turbo mode.

I check the chain because I think it started slipping but I don't know for sure if slipping or is it a misaligned derailleur?
It feels like slipping but only on some gears definitely not on the lowest and not on the highest.

Chains do wear more quickly on a e-bike, how quickly depends on the riding you do. It’s always cheaper to replace a worn chain than a worn drive train.
The nice man here shows how to use the tool. AFAIK, there is no need to push the pedal down while checking for wear.

It is common for people using Ebikes to stay in the same gear, which may be why you find certain gears slip. Usually it's the top two gears, to the extent that we can now order and replace these gears on a cassette for customers.

As @Punkawallah says, best to change the chain now than the entire drivetrain later.

They can do on a mid drive (crank motor), but usually wear slower on a hub motor.
On a mid drive all the motor power AND the human power goes through the chain. On a hub drive it’s only the leg power so the chain is getting less force than on a normal bike.

That’s knackered, if it’s like that on the 100% marker then it’ll need a cassette as well

600miles is a ridiculously low amount of miles from a chain and that one looks completely shot seeing as it's over 0.75 worn!

My wife has an ebike which has done 800miles and hardly any wear on chain so not sure what happened to yours.

Got about 2000 miles out of a KMC E-Bike Chain. Just had it changed for a Shimano E-Bike chain after it reached around 0.6 - 0.7, cassette too.

it looks like the same tool however mine won't drop into the gap (inner link) even with the other (anchor) side free.
I call these inner/outer link, perhaps there is a correct term for that.
On his video he dropped it into the inner.
I can only drop it into outer link, it won't drop into inner when anchored or not.

I know what you mean but this is not in my case. I shift a lot. I know some e-bikers when struggle change to more powerful mode rather than shifting gears.

From what I can see in your picture you are using the tool the right way, but I see what you mean when I look closely at the video. I have no clear Idea why the tool would hit the ‘inner’ link.

Mine has done 11,000 and a bit and has had 2 chains

mid drive ebike - so everything goes through the chain

I seem to remember the first time that the bike shop bloke said he had put a better one on it that it came with

 

[Bristolian]

If that's not the original chain then (depending where you bought it) it could well be a counterfeit in which case 600 miles might not be too bad.

I got a lot less out of mine, maybe as low as 2500 miles but I didn't really take care for it as much as I should. This new one will be cleaned a lot more regularly.

I looked at the manufacturer's inventory and I ordered exact parts from ebay KMC 8 (£10) chain and Sunrace bike cassettee sprocket CSM55 11-32/34T (£20).

Did the chain come from a reputable supplier?
The fact that it came via Ebay is no guarantee that it is a real KMC chain. There are plenty of fake chains and cassettes out there.
