I've just got a cannondale frame off a friend and I as trying to work out what it is.
I'll pop some photos up to help as soon as i can but for now i'll describe it.

Its a blue hardtail, disc mounts only, came with a lefty fork that just said lefty headshock on it.
the frame says "optimo" on it which I thought was the model but it seams they do a optimo and a furio in different models.
I would guess it a 2005 due to the kit left on it.
Any clues would be appreciated
Oh i've checked the cannondale site but couldn't find it
