Mine is silver grey...
Wow. Very interesting! Boy, I am learning fast here. Hmmm. Well I just bought the Royal 886 off eBay and it came with a silver grey roll. I didn't scrutinise it but it has hex ends. Maybe it is! Looked like metal. I just like premium quality so I presumed that carbon fiber was the way to go.
I will have to check and get back to you on that!
Thanks for all your help!
