As a tool and die maker, CNC programmer, and machinist, I pride myself on being discerning when it comes to machined parts. I have thoroughly examined this component and found its craftsmanship to be exemplary, with fit and function meeting high standards. The quality of the part, particularly considering its complexity, reflects the skill of a proficient machinist. Although I have yet to have my son test it under its intended conditions, I am confident in its performance based on my observations thus far. I look forward to purchasing additional components for future bike projects.
