Polo style Diamant fixie 56cm on the top

eyebrows - you obviously didn't build it up properly

• no grease, no oil, no thread lock (which only acts as a lubricant at higher torques) white spirit on both threads - wait until dry then tighten up nice and tight using the chain on the bike as a chain whip - rotax or whatever it's called (BB lopck nut is pretty superfluous but add acording to taste)
