I had luck today overtorquing the expander and under torquing the top cap. Like 14NM on the plug and like 2nm on the top cap. I finally was able to complete a 2 hour ride without slipping but it still was a bit loose, only noticed small amount of play if I applied the front breaks hard or cornered quickly. The expander plug and integrated handlebar bolts are so stripped at this point lol. New bolts and plug are ordered, but I think I will have to live with this for the time being. I am getting creaking from the seat clamp, I see Patty says the carbon seat clamps are flawed... I am not looking to spend more money on this thing. Looking to swap to a different frame asap. Maybe a Allez Sprint or get something from winspace next time they run a sale.
