Does anyone know of an option for a light weight setup that will still offer support in a carbon steer tube? The one in my Giant Propel is pretty chunky.

I prefer the JRC components superlight expander

https://www.jrc-components.com/products ... t-expander

It has more points of contact...but is about 6g heavier

There a few threads devoted to this very subject

Also quite a bit on YouTube

He needs 1.25, not 1.125 . Another option:

I have one on my Canyon. I would say it works very well, but it doesn't really have to do much does it!? Other than hold a bolt in the steerer tube. A bit fiddly to set up, but once fitted it's been fine.

My main concern was supporting the carbon steer tube where the stem clamps it but I assume if I place this where the stem is it should work. The oem giant pice is a boat anchor and quite long.

I have the similar boat anchor in my BMC. After this post, I decided to leave it as is.

I read through that and watched the two videos. The first one the guy says that the expander plug in the giant overdrive setup is no good or not good enough for him? Not really much else in that thread other than opinions and light weight options.

I think if I just make sure that the expander plug is where the stem clamps the steer tube and I don’t hulk the stem bolts down it should be ok? Maybe keep the metal sleeve?
