I'm not too big a fan of compression plugs, or at least the profile one I've used. It wouldn't preload my headset tight enough and after a few rides it would loosen up, which obviously isn't any fun to ride around with a rattly loose headset.

I just stumbled across these head lock / stem lock things, which from what I can tell get great reviews... on mtbs. I didn't find anything on somebody using one for a road bike, and I'm not sure if they're intended to be used with a carbon fork at all. Has anyone used one on their carbon steerer fork? Or can anyone recommend a compression/expansion plug that stays put and allows ample clamping force without needing to be adjusted every few days?
