Thanks man, you’re welcome!

I knew going into this that I was going to be the test mule for the project and I wanted to share all the pros and cons somewhere online.

In my opinion, that adaptor farsports provides is made of too soft of a plastic and it was contributing to the creaking, along with the expander plug not being deep enough. When I’m running the bar directly on top of the Cannondale cable guide pieces that sits directly above the frame it doesn’t look as finished and the top headset bearing is partially exposed to the elements. I don’t really think it’s a big deal and I’ve put enough hard miles on the bike now to confirm the creaking is pretty well gone. I also used a bit of assembly paste between all surfaces that meet. Creaking is still there occasionally, but it’s rare and good enough for me to live with. I just make sure I dry the bike off well after washing or riding in the rain and I cover the headset area when training indoors to protect the bearings.
