no - i don't have a caliper on hand. however, the expander plug has plenty of additional expandability - i have no problem getting it tight, it's just that it's not gripping. I can't get the top cap even to 5nm without it being drawn out.bremerradkurier wrote: ↑Thu Jul 19, 2018 3:39 pmHave you measured the inner diameter with a caliper to see if it is in spec and concentric?inertianinja wrote: ↑Thu Jul 19, 2018 1:20 pmanyone know the torque specs for the expander plug that comes with the FM066?
I can't get this thing to stay put in the steer tube. Used Park Tool friction paste, torqued to 6nm (and a little more), but when i preload with the top cap the thing just pulls out, leaving the headset loose.
I also tried doing this with the parts clean and dry, but still preloading the top cap just draws it out, gently sanding the inside of the steerer tube
Or, maybe a better option out there?
Edit: I just tried an expander plug from my other bike, which is a KCNC-style expander with the same knurled edge. Same result, pulled out.
I emailed the frame seller, but i'm tempted to just put a good amount of torque into it so it stays - I literally only need it to stay put for 5nm!
Maybe I'll try an FSA expander first.
