Mid-drive chain and drive train wear measurements

It's a right effort escaping Vengeful Vermin Virgin Media. My trusty OnePlus phone has recorded all conversations (records everything automatically anyway). and I warned them before it did so.

There's another dark pattern when leaving the Vermin Virgin - when you sign in to pay your final bill, you're presented with a bill without the refund (30 days notice required, so you're supposed to be refnded for whatever number of days you won't be using), but on the next screen the refunds are included, yet on the following screen the refunds disappear and the full bill is auto-entered at the payment stage. I entered and paid the smaller amount with refunds included (£7.26), let's see if they go away. I'm certainly not giving them any more money than that, to wait for a refund some time in the future when they feel like refunding me, and having use up more of my remaining time on this planet to chase that refund up (Mars awaits). Customers desperate to leave might make the larger payment perhaps.
With my new broadband provider Smarty, to cancel I'd simply disable that automatic payment on the Paypal website. Practically, it's lower speed hasn't made much difference, and it doesn't disconnect several times a day (sometimes for hours) like Vermin did. Damned saga.

Any idea on how many miles you did in that year?[
hmmm, that's a good price for KMC - I'll need to go take a look.
So how long had the cassette been on the bike (and miles done approx?) and what make/version was it?
As a rule of thumb, I get around 4,000 miles per KMX X9 chain and I go through at least 3 chains before a new cassette is considered. Again as a rule of thumb (not my rule but what others have postulated) chain rings might need changing after 3 cassettes.
Those rule of thumbs were 'held beliefs' from the unassisted cycling world so an ebike rider using oodles of power through their mid drive motor will see higher levels of wear (as in 'how long is a bit of string'?).
Keep an eye open and be prepared to add links, and the 114 link unplated KMC X9 can usually be found for £12.99.
Same goes for SRAM basic 11 speed chain.
I only got three chains worth of wear, not three cassettes, out of my first chainring. 14,000 km in numbers. A 1x system with ebike loads is always in use, as compared to the sharing of time across several cassette 'most used' gears, so not overly surprising.
I've managed to pick up spares for my Shimano e5000 for around £22 on average, so not devastatingly costly.
if i wore out parts and motors like that id not even bother with one of these bikes seems from all the posts i have seen over the years means a dongle makes the motors last longer as not putting massive stress on the drive train and motor with no power over the speed limit.
i had over 10.000 miles on my old motor.
got my moneys worth out of that motor, new bearings and transfer gear it is still going today, i was going to keep it but as i have a kiox display means if i swapped motors back down the dealers for a can shake for 30 bloody quid to push a button cos the sn has changed
I wish I could give you an exact answer, but chains are so cheap that I don't bother to note how often I change them. However, looking at my posts on this thread and my ODO, this last chain lasted about 1,527km, which I changed to sometime after 29th April 2022. I suppose I get through chains more often, because of high levels of assistance and hauling of heavy trailers.
FYI @guerney - New cassette at 3,986 km. (Else I won't remember, and I very much hate going through receipts.)
Looks like I got one of the last X8s at £12, new stock in two or three weeks, sorry about that. I might have ordered the actual last one, because I was unable to add two to the cart. Do Amazon honour the price quoted when you pre-order?
As for chainrings, it's time may be soonish... I'm tempted to buy a Bafang spider converter wotsit, in order to use something like a 58T, to replace my Bafang stock 52T, now that I have increased the current limit of my controller to 18A (15A previously). Tempted by my speed obsessed younger self mind.
"SRAM 8 Speed Cassette 11-32T CS PG-850 Silver, 00.0000.200.396". £15.50
3,986 km or 2,476.79 miles.
Hmmm, good point. Maybe I should change my chains sooner.
I don't know what you're talking about. My chain is perfectly clean.
The new cassette is embarrassingly shiny aaarrgghhhh
I'll add that task to my bulter's cleaning roster. There's no way I'm touching that thing.thats called grinding paste

Life's too shot to be putting those on, then taking them off, to put new ones on again... I'll just buy cheap chains and cassettes more often.Blue Nitrile Disposable Gloves - Medical Grade - Powder Free

p.s. Swarfega.
While begrudgingly giving my bike it's rare year plus several months clean... I discovered that Aldi's concentrated non-bio washing machine liquid (diluted a bit) cleans my hands more thoroughly than Swarfega!Blue Nitrile Disposable Gloves - Medical Grade - Powder Free

And not only that - it conditions (says so on the bottle). It also did a spectacular job of cleaning black oily grime off my bike, that and 90% isopropyl alcohol. Might have conditioned too, I can't tell. Hypoid 90 is excellent chain lube, but it does spatter... I considered mixing in a knob of buttery Aeroshell 22 to thicken it up, but I expect that'll be worse than the 4 in 1 I was using before the Hypoid 90, depending on the ratio.

Hypoid 90 is excellent chain lubricant, but it does spatter... therefore I've thickened it up a bit: 1 teaspoon of Aeroshell 22 + 3 teaspoons of Hypoid 90. The result doesn't seem much thicker. They don't mix easy, had to stir with one of those small horsehair electronics brushes. Seems to work fine so far, but this could change in cold weather. If it doesn't work out, I'll simply wash it off... and if nothing else, I'll be increasing the odds of ever using up my lifetime supply of Aeroshell 22 (huge tin) from zero to unlikely.

Yep, you're right - Aeroshell 22 and Hypoid 90 mixed didn't work out well lol. Worse than 4 in 1. Ended up with treacly AeroHype 112.
They're back in stock at £12:
