I agree very difficult to install

I managed to get the caps on but I am not sure if it stripped on the way in. I hope I never have to take it off to find out. The BB does seem to be of a high quality very smooth

This BB is very difficult to tighten

The caps on the BB require the use of a Parktool BBT-18 ( but this tool does not have an opening large enough to fit over the BB's spindle. The only other option is to use the Pedros wrench ( which is better for this BB. Surprised that there is nothing in the description about this issue, as it's a big deal if you want to properly tighten the BB.
