Hi guys, I need your help. I’m currently changing the handlebar and stem on my GV201 gravel bike. While disconnecting the brakes to redo the internal routing, I noticed that my current setup uses olives and inserts with O-rings (as seen in my photo).

However, the LTWOO tutorial shows them without O-rings.
Before buying replacements, I did some research and everyone told me they should be like the ones in the tutorial—without the O-ring.
What should I do? Which ones are the correct ones? If I do need the version with the O-ring, where can I find them? I can't find them in stock on AliExpress, and I’m not sure what keywords to use to find them on Amazon Italy.
Thanks!

Unless there is complete designchange between the R9 and ER9 - which i doubt - standard Shimano BH59 should work without any problem. No O-ring needed.

Yep get some B59 olive https://it.aliexpress.com/item/1005006123044004.html (https://s.click.aliexpress.com/e/_c3SGxwuv) and a press https://it.aliexpress.com/item/1005005989933218.html (https://s.click.aliexpress.com/e/_c315XhRL) and you are good to go

I ended up using BH59s... we'll see if I end up hitting a wall ;D ;D
