Potentially but I wouldn’t personally.
I’m thinking of running full length compressionless and maybe putting two joins in with a female to female ferrule so I can use a short ~10cm length of non compressionless, more bendy bit for around the BB. It’s really fucking tight without stiff cables.
Never seen a CAAD12 bb up close but could the rear cable just come out the bottom of the bb instead of going through the chainstay?
