3DF and BB86.5 .. Rotor says use 4130 BB .. would I need any spacers?

This frame.

Thought most treks were bb90, which won't work with 30mm axle.

If it is bb86 then yes the 4130 bb will work. No spacers needed on mine (giant tcx) just a slight tweak to the preload ring.

Perfect! Thank you. Its defo not BB90 .. I think BB90 is carbon only with Trek.
