PF30 sits the bearings in a plastic housing in the vain hope that it might stop the bearings from creaking.
Loctite is the 21st century evolution of gaffer tape, which was the late 20th century evolution of steel wire... when you need Loctite to keep things together, you know the engineering is censored
They might also want to check the rest of their bikes, in case Loctite has been used elsewhere and needs to be removed; the bolts attaching disc brake calipers to frames, and rotors to hubs, seem to be common culprits. come to think of it, stem bolts seem to come pre-loctited too :shock:
The difference is that loctite is used on threads as a preventative measure, or in other words it does what it's meant to do... but it's not essential... the screw will work fine without it. My point is that if you need loctite to stop something from creaking, then you know you bought a pile of censored ... and you agree on this... anyway, off topic... :shock:
In terms of serviceability, robustness and longevity, I've yet to see an improvement on the steel BB cups screwed into a steel frame with loose steel ball bearings and a square taper crank, that I had when I was a teenager. It was probably heavier and flexible than modern bottom brackets, but there wasn't much to go wrong. Mind you, the cottered crankset that preceeded it was an absolute disaster!
