BB Advice please part 2

[roger44]

I have a FSA SL-K LIGHT Carbon crankset with 24mm spindle that I need to fit into a threaded frame.

The frame currently is fitted with a FSA CRANKSET MEGAEXO 19MM SPINDLE. Thread is 1.37x24. dist across the bearing is approx 90mm

I assume I can unscrew the existing 19mm spindle bearings and screw in 24mm bearings

any help gratefully recvd,

many thanks from 'easily confused'

Can't really comment with any authority but you should have a BB which comes with the crank. If you don't it seems to be a case of finding one. Thread should be common to all. The FSA series 8000 appears to be the one you need but all the sites i turned up for these say no longer available. Shimano hollowtech won't work.
Sorry I can't be more helpful.
