Morning

So planning on swapping the chainset to Shimano, using a rotor bb30 to 24 converter. Do you remove the pressed in.bearings to fit? And does it impact the q factor as the bearings are now external?

Second q, would there be any issues with drilling the ends of the r bend bars to make them internally routed and improve cabling? How easy is it to remove the sram shifters?

Q factor should be unaffected, as its governed by the axle length.

I’ve seen a few people drill tt bars for internal routing. I never did it as it was such a pain, heat shrink or a roll of electric tape is just as effective, but not as pretty.
