Best Overall: FSA steerer Tube expander plug

Buy on Amazon

Fsa steerer tube expander plug is the epitome of what a great plug should be. If you have a 1 1/8 carbon steerer and need an expander plug, this is a great choice. It can be used on a carbon rigid fatbike fork. This works in the same way as a star fangled nut and top cap would. The plug tightens radially, separate from the top cap which tightens axially for just the right preload on the headset. This lets you have the plug at the same level as your stem.

This is an easy part to remove and install just drop in and cinch it down, note that this is only for carbon steerer tubes. It would be perfect with a full carbon fork.

• Easy to understand, install, and adjust
• Works perfect for a carbon steerer
• Easy to install and stays firm

Best runner up: Whisky steerer Tube expander plug

Buy on Amazon

The whisky steerer tube expander plug is the best feature-rich plug on the market today. WHISKY’s top cap compression plugs are reliable and easy to use. It exposes the ‘silver’ aluminum compression part which has a 4 or 5mm bolt through it that expands into the steerer tube. It functions the same as a star bolt where star bolts are commonly used in alloy steer tubes while the plugs work in both alloy and carbon steer tubes.

The aluminum part is basically a star nut you don’t have to pound in, just expand it until snug, and then pull the fork up with the top cap bolt. It is easy to install and longer than most compression plugs to help support the force of the stem clamp. This compression plug is for forks with carbon steerer tubes, and you should not use star nuts with those. It offers great support and function.
