Steertube Compression Device
 

Has anyone installed one of those steerer tube compression devices that are supplied with carbon forks onto an alloy steerer tubed fork?
If so, how are you getting it to stay put? We install, torque, and as soon as we start tightening the headset preload, the device just pulls out of the alloy steerer tube.
Are you suppose to locktite it in place???

Here's a link to Ritchey's version: (using a Felt version which is similar)

Thanks

Why not use a star nut, bolt and cap?

A carbon steerer tube is thicker wall, so ID is smaller ..

you need to find a compression piece that expands further out,
they are not all the same.

And/or, you may bond a liner sleeve into the steerer tube to decrease the ID.

nope, but, you might DIY on that ... try a piece of old innertube.

how about carbon assembly paste?

Try expanding the plug out just enough to give it a snug fit as you slide it down the tube. Also try a drop of oil on the threads where they pass through the expander part of the plug. In other words, you need to add a little friction to the outside of the plug and reduce the friction at the threads.

As fietsbob mentioned, expander plugs come in different models for carbon and metal steerers with the ones for metal being larger in OD due to the thinner walls. You could shim your plug with inner tube rubber or similar material to give it traction.

Thanks guys, it worked!
Shimmed the tube with a small sheet patch kit rubber, worked great.

Good deal!
