Hi Don. I had fabricated a head set from spare parts with a Teflon bearing surface. But in trying it find that loosening the headset and applying high viscosity lubricant results in just as smooth a movement, with no play, as long as you get tightness just right on Allen screws. The only problem at all is that the Allen screws loosen a bit after a ride or two, introducing play. So what I am doing in the spirit of “no-harm” to the bike (I.e. leave every component of Kickr bike as is, not messed with) is getting another stem and a riser post. Riser post will attach tightly to where Kickr stem was, and new stem to riser post and will articulate there. (I like my bars a bit higher anyway). I will then slightly flatten (or use locktight, or whatever it’s called) threads on those new stem screws so they won’t turn too easily and not on their own. I’ll post photo when done. But basically, loosening screws on current stem and lubricating works fine. I just like the idea of leaving original parts just as is and not introducing wear and tear. But the reality is that I don’t see any additional mechanical stresses introduced. BTW I got hold of Wahoo development. They are intrigued and asked for photos of what I am doing. Bottom line: having a blast on Repack!
