I would use them for races.

My experience is the same as many have explained above. I used the skewers a few times then stopped since it was clear they would round out the bolt head soon. There really should be a replacement program with re-designed bolt heads. In general I'm a fan of Tri-rig equipment.

Try these:

Trying to pay for replacement bolts through TriRig Misc. Payment just gave me an error dialog box. The bolt heads really need to be torx to provide more contact area for torquing down.

I was one of the early buyers. A deeper head would make these perfect, so I'm glad that's changed.

I have concerns about longevity with a softer metal and only a 4 mm hex insert. I see why keeping it a simple size of wrench that everybody owns is a good idea. Part of me thinks a T25 would have made more sense, but I'm a non-engineer on an internet forum. I grabbed some high end bits from a specialty hardware store and used a fresh one for installing these both times. I have a handful of new Bondhous hex keys too and used those to loosen. I could see an old or low tolerance hey key camming out these skewers based on my experience with ti bolts in stems. That's the closest thing I can find to a downside right now. The possibility of camming out the skewer. Nick will probably come correct me that they're using some super titanium to prevent that though.

Well look who quietly updated the Styx over the summer. Goodbye less-than-ideal 4 mm hex interface.
