My drive-side chainstay is cord wrapped.

I use the reflective Ironwire that Lawson makes for Durston, tied in a spiral French hitching wrap. It helps to protect the chainstay, but mostly it looks cool.

Chainstay Cord Wrap

At 2mm, Ironwire is slightly thicker than the 1.7mm Kevlar cord that ships with the FiberFix Replacement Spoke, but my guess is that I could unwrap some of this cord and use it with the FiberFix hardware. I have yet to break a spoke this eyar, so I haven’t had an opportunity to test this.
