Bought a new tap, fresh bottle of cutting oil..ran the tap, actually went thru from both sides pretty easy..bolted RD to frame and.........same thing along with some really colorful sparks. So...swapped for a steel bolt. And all seems ok..still not sure *** is going on..I'm gonna blame it on Ben.



Doohhh!!

On my Ti bike I pull my BB and RD once a year and re copper paste. After reading this thread I just popped my RD and re pasted. It's a DA Di2 RD, that has a Ti bolt, right?

Same Ti bolt, or did you try a new Ti bolt?
[Edit: Never mind, I see you used a new bolt]

Funky design

Merlin decided to put in a top and bottom stainless sleeve on their integrated headsets/head tube design

I am questioning at this point / it is bonded and was never meant to be removed in the first place. These inserts are what the bearings sit on / cane creek is-2


Curious if ti will eat the stainless over time, like it eats the shimano cups 6500. I have had large chunks of bb cups disappear over time?

maybe i am wrong,

this looks like ti insert. anyone know?

curious

They (merlin integrated sleeve) were designed to be replaceable. CK inset is a traditional/much better solution.

what specific tools need to pull and push the inserts, curious. King specific?

oh, do you know whether the original sleeves are ti?

They were stainless. Not sure about the tools, but the LBS said the inset install was super easy and gave me back the old cups. They were treated. I can shoot a couple of pics with the inset installed if you want.

Is the forthcoming package a CampMAgNolo or a SHEmano?
