So my road bike has an Edge fork with their carbon expansion plug. Got it nice and covered in some Finish Line carbon paste to keep it from slipping. Edge doesn't give a torque value for it, but I try to keep it pretty snug. The problem is, if I properly pre-load the headset, the thing gets loose in a matter of a few rides, and the expansion plug has slipped a few millimeters. I torque my Thomson stem to spec too. Any ideas on how I can keep that damned plug in the fork, or keeping the headset from coming loose? It seems like once the stem is tight, the headset shouldn't budge. Maybe it's slipping around a bit on the carbon steerer? Anyone had this issue before? Sometimes I wish I had a press-fit headset and a metal steerer....
