Wha'ts the story behind this bike? It's equiped with full vintage Dura-Ace groupset and it looks like from the early 90s. I don't think it's just stickers. I've found it on local listings website
Maybe a sponsored rider or just a fan at one time. As far as I know, Oakley never make bicycles, just parts to go on them. Look up the rider and see if you get any hits.
