This bearing set seats directly into BB90 (Trek road) frames, and will work with 24mm cranks.
Check out our BB95 bearings here if you want a more durable bearing for a Trek road bike.
These bearings do not require the use of Loctite (in fact we recommend against it). Just use a high quality waterproof grease, we recommend Morgan Blue Aquaproof Paste or as we call it 'shut up grease'.
