The Good: The bolts they stay in shape well they don't strip and the bars and forks don't move at all. it grips tightly.
The Bad: I ride brakes and i usually ride my stem upside down. the colony gyro plate doesn't work when the stem is upside down.
I would consider every single part of this hub. it is amazing for a Stem and it is light as hell. it is strong. consider getting this
