Topline (Micro d) Crankset on Manitou FS - Bottom Bracket Trouble - Manitou Fs expert needed.

[The Judge]

Hello,
I am installing a Topline (Micro D) crankset with Speciality TA chainrings on the 1993 Manitou Fs. The bottom bracket on the pictures is 131 mm (Bsa 68 mm), unfortunately it touches the frame. I would need a much longer bottom bracket? Aren't there 137mm/140mm bottom bracket ? The other Topline cranksets also have same problem on the Manitou Fs?
Thanks for your help !

Yes. It looks all a bit too close. Longer axle bb needed. With a bit of flex (even if the drive side wasn't touching) the non drive could contact the frame.

Its not an iso taper or anything strange?
