Yeah, and it's spinning smooth as a champ even after... a good 8 or 9 months. I'm actually pretty impressed with this one, my last one got like 3 months of rain before crapping out IIRC.
The nice decorative holes in the BB shell that Alien uses seem to let a good amount road grit in and gunk up the threads during a downpour, so I proceeded to clean everything out, re-lube and tape over the holes with aluminum tape.
Of course it could have been loose cranks too... I just took the whole shindig apart and put it back together relubed and clean, the bike is silent again like I like it!
