I'm interested to hear what kind of mileage people get out of their bottom brackets in foul weather.

I have various Shimano HollowTech II bottom brackets on most of my bikes, just because that's what the cranksets I wanted to use required. My 2013 Jake came with a Tiagra bottom bracket, and after 3000+ miles it seems to be fine. When it wears out I'll probably replace it with an Ultegra or even Dura Ace model just because the price differential is fairly small for this part.

I've got a Dura Ace HollowTech II bottom bracket on my CX race bike that has held up through 20 races or so and, let me tell you, compared to a muddy CX race a rainy commute is a spa day for the bike.

I have worn out a couple of FSA MegaExo bottom brackets (both in less than 2500 miles), so it's not like I'm just putting up with gritty bearings. The Shimano bottom brackets just seem to handle the conditions I ride it.

I like the idea of square taper bottom brackets, and I have one on my Long Haul Trucker. I'm just wondering what kind of mileage people are getting out of the cheap-to-midrange models.
