Any photos to see the wear?

No, I'm afraid not; some of the chrome plating came off the ratchets—specifically on the outer edge, and not on all of them. A few tiny flakes ended up on the paper towel while I was removing the old grease.

they're std Dtswiss but new model with inner groove and not the old model without.
I swap 3 different ratchet from different wheelset/source without any problem.

The spring are not all equal, some springs are not compatible with grooved spacer (it's a matter f 0,1mmm)
There are 4 different set of springs:
conical springs (old model)
cilindrical springs (with round wire)
cilindrical springs (with flat wire)
cilindrical springs (with flat wire "double loop")
+additional trick: spring on one side, teflon ring on the other one

Is the difference from 54 to 60 noticeable? Yes.

The crisper the sound (in garage) the higher the headace in long alpine descent...

if you match correctly you can manage the balance between drag/sound...

Thanks for the reply. I didn't think it was so complicated; I thought it was standard. Anyway, these ones from Ztto look the same as mine.

They cost a little over 20 euros.

Good morning, after months, I’ve finally managed to finish assembling the bike. I went for a short ride to check everything was in order, and I must say the assembly was relatively straightforward – it’s the first bike I’ve ever put together. The weight, including the temporary pedals (some old Timerxe ones), is 6.920 kg.
I’d like to ask you a favour: could you recommend a Garmin mount for the SL8? Thanks.
I bought one on AliExpress but I don’t like it very much; it hangs too low over the ground.
Thanks

p.s. Can anyone explain how to upload photos directly to the forum? Thanks

I bought Ltwoo barbs with gaskets from Ltwoo on Aliexpress just to be sure.

Do you have an aliexpress link where you got it?

What wheels are these?

Sorry, I'm just seeing this post. The wheels are Carbon Speed 50mm, 26mm channel, 5mm spokes, raw finish.

Good morning everyone, I should be receiving my Lexon crankset with a 29mm spindle any day now. I ordered it without the double chainring. Could you give me some advice on what to buy? I'll make sure it's compatible with the stock crank spider. Thank you so much.

I saw Stone and Pass Quest chainrings on AliExpress, but I'm not sure if they're compatible with Lexon, definitely Shimano. Thanks again.

I wonder if your 14500 battery is too short. You’d think they’d all be the same size, but some of them are slightly shorter than others not letting the battery holder make sufficient contact with them. Had isssues with my EGR, until I replaced it with a slightly longer battery. No issues since then.

very likely

I just ordered the erx one, with oversized cage and ceramic bearings from pandapodium
