This was the (my) initial post in this (my) thread:
My hope in this thread was to have a conversation about pros, cons, choices, and experiences with spokes not made of steel. We've talked about Spectra fiber and another type of flexible fiber. There has been some mention of titanium. The latest contribution were about carbon fiber/Kevlar spokes. All very much on topic and appreciated.
As others pointed out, there are titanium spokes out there:
TI-DYE High-end and super light bike spokes
I'd love to have a wheel or three built with them, but I doubt they're useful for anything beyond gratuitous bling.
