Are my jockeys worn?

Got your money's worth there.

Yes, they sure look worn to me. I have not seen jockeys wear like that before, maybe its the make.
These are more like mine.

For the avoidance of doubt, the ninja throwing star on the left is the worn one!

Shifting was a bit crisper with the new jockey wheels. But It wasn't a massive change, I might bot have noticed if I hadn't known they were new.

I have holes in my jockeys but Santa didn't bring me any for Crimbo ?

They are OEM Shimano. 1945km out of the little feckers!

They wouldn't normally wear to that extent in such a short mileage.
do you run your chain dry or something?

Is it me or does the cassette look worn as well? ?

 

[TPEHAK]

If it works it is not worn.

it does. but a lot of what you're looking at is shifting tooth profile. If you look at the sections between each tooth you can see some look flat rather than nicely rounded. But even that is no indication. Depending on particular cassette

I never run my chain dry. The last couple of month’s weather/conditions have probably been a major contributor. I replaced my front and rear brake pads in October. Both f and r were even worn from summer riding. Checked them last week and the front was slightly worn but the rear was almost worn out. Mud takes its toll alright!

The cassette is no way worn. It’s only 200-odd miles old. The previous SLX was swapped at c. 1700km that also didn’t really look worn. I only changed it as the chain had stretched a bit so needed replacing along with the front ring.

I have to say the shifting didn’t really improve that much considering the £200 outlay for the replacement drive train. Replaced chain/front ring like for like but went XT for the cassette. A bit odd Giant fitted SLX cassette considering everything else is XT?

Maybe when the new jockey wheels turn up that will change and it’ll shift like butter

See my post above - I tend to go along with that. New cassette, chain and front ring did not take it back to how it shifted when it was new. That said all my bike over the years have never maintained the box fresh shifting of the first few weeks of ownership.......I am quite good at setup too.

Maybe time for a 2021 bike

Hardly surprising if your jockey wheels were looking anything like they do now.
When you fit your new jockeys check the mech function is smooth and slop free and straight as well as hanger alignment, chain length and B-tension position. Also check your gear cable inner and outer and replace if needed.
If it's not shifting well something is worn, sticky or out of alignment.

A wee money/time saving tip for cables:
when outer gear cable is old/well used it tends to fray at the ends inside the ferrules causing friction and vague indexing. but rather than replacing the whole outer cable each time this happens you can often get away with just removing the ferrules and cutting the first and last 10mm ish off. (you'll need proper cable cutters) you can then flush out the outer and replace the ferrules and inner cable for new ones. Just make sure to check the inner now moves smoothly. (a lot less hassle than replacing most full internally routed outer cables, especially on Ebikes)

I thought you were talking about your undies! We called them Jockies in New Zealand. A brand name.

Gear cable replaced a few weeks ago by LBS. Thanks for the info . New jockey wheels arrive tomorrow. Will fit and see if they make a difference. If they make that much difference I’ll replace them first before the rest of the drivetrain

Mine have worn exactly like that every time. XT 11 speed.
