Variant Shimano BB-RS501 stredové zloženie, 68/70 mm, BSA, Hollowtech II

It works as it should. The hole for the cleats is slightly larger than the SM-BBR60 (easier to install cleats)
Freewheeling/friction is slightly worse than with octalink 4-edge compounds.
Also fits 105 wheels (tested on 5800 and 7100)
I recommend using a rag under the Shimano wrench, otherwise the teeth will be imprinted there. There are some plastic shavings on the factory grease from manufacturing, I removed it and put a new one.

Variant Shimano BB-RS501 stredové zloženie, 68/70 mm, BSA, Hollowtech II

Relatively light, easy assembly, pre-applied grease, cranks turn beautifully, we'll see how long they last, but with my cycling I believe the bike will be morally obsolete rather than a broken bottom bracket

I changed the wheels from square to HII, road, along with tiagra chainrings, it's working fine. We'll see how long it lasts, so far it's been running smoothly for over 700k.
