@ascentale @xtaran @bikenite A2: the first Shitmano 8 speed hub that failed after 5000km was unexpected. Warranty replacement.
The replacement also failing after 5000km was less unexpected. No warranty despite being inside the 2 year promised warrenty period.
When the third one failed also after 5000km it was 100% expected.
A Rohloff would have been cheaper.
