yep 231 in silver or CD available with/without ceramic - had them in silver on M900 when they first came out. Great rims - till I punctured in a race after a week, dinged the rim and cracked all the ceramic coating. doh!!! :evil: :evil:
Sunset 217s were a bit later, about 95 I think.
There were many rims in black early nineties - the Energy M7 Mavs were black and these were late 80s IIRC. Campy etc black too.
