I found a very positive review of the Ninja, so it seems a good solution to a problem that nobody asked for (i.e. I had zero issues with english threads, so I had no problem, but then the manufacturers went press fit, and they creaked, so now we have the ninja).
I think if the industry wasn’t moving back to threaded, then i would go Grizl. But as the industry is moving back to threaded (english or T47), I’ll hold off until someone releases a bike similar to the Grizl, but with a threaded BB and no Future Shock.
