Square tapered can’t be taken apart for cleaning, but they look more sealed too. The square BB I’m replacing is 10-year old with about 12000km on it and has no contamination visible, even after breaking it apart.
The reason I’m replacing it is because it’s got some play and misalignment. As I’m still overweight, with 114kg (down from 157kg, all 43kg lost on this BB), I’d thought about upgrading to Hollowtech, if the durability factor worth it.
