Fondriest F900 MTB - Bottom Bracket

[RustyHWR]

I have got a Fondriest F900 full carbon hardtail frame, but cannot find any information on what pressfit BB and crank to use? If there is anybody out there with the same frame that can help please? I tried the bike shop that brought them in originally, but was told they don't know. I tried to mail Fondriest but never got a reply. I ran it with a pressfit GXP bb ( Lyne Pulse crank) and a direct mount non boost chainring (6mm offset), but then my chainline is all wrong. Drive side crank arm to close to chainstay. Tried with a Pressfit PF30 BB30 crank with no success.

Any info will be appreciated.

My guess is that it is a BSA 41mm bb of either 73mm if cups are external or bb92.

The Crank arm touching the stay is likely either the Crank not being spaced correctly or the q factor is too narrow for the frame.

please post pics of the Crank installed and from both drive and non drive side to illustrate Crank arm clearance

Thanks. Will post pictures when I got it all assembled again. Think the Q-factor is too narrow.
