The definitive thread for 1-1/2 Internal Routing headsets... (or) wtf tho?

Thanks for sharing! I did see that one just after my post. Helpful to hear you've had a good experience with it. I have a. Electronic groupset so I assume I can just find some 5mm plugs for the unused holes?

I presume you can use some frame gasket plugs. I'd still adequately grease the bearings just to prevent any moisture build up.

Also looks like ZTTO has the same headset cover with different size c-rings:

SPCycle probably sells the best headset cover due to the waterproof gasket port. I'm using the same one on my R088 frameset.

FSA SRS, Acros ICR and Ritchey also make semi-integrated top covers with rubber blanks.  No experience with any of them but it looks like you make your own holes for the first two, so presumably a better seal and no bungs required
