Ok so i know you can get 1" comp plugs, the bike store even had some. Issue is that most kf them are for aluminium steerers which have a bigger center hole and after trying a couple they didn't seem to fit into the hole of the reynolds fork. So I'm looking for something made specifically for a 1" carbon steerer.

The guy at the lbs told me that if I'm paranoid I can just keep checking on the steerer by removing the top cap/stem and if it doesn't get worse then it'll be fine.
