I recently ordered a 2019 Cannondale fat caad 1 with the lefty Olaf fork. Got a pretty solid discount as the 2020 stuff is starting to roll in. Just checked out the Cannondale site and saw that the 2020 fat caad 1 is announced and is a pretty basic rigid fatbike. Looks like Cannondale is giving up on their short lived experiment with the lefty Olaf?
