The new seal construction is the real winner here — after a few rainy rides there's still zero grit getting past it, and the crank spins noticeably smoother than before. Installation was straightforward too.

Swapped this in after my old bottom bracket started creaking, and the difference is immediate — the cranks spin noticeably smoother. The new seal construction seems to be doing its job too, since it's stayed quiet through a few wet rides already.

The new seal construction actually holds up through wet winter commuting, which is why I switched to these. Only gripe is the price, but the rotation stays smooth after a few thousand miles.
