Like a well-used Leica rangefinder, there is something undeniably comforting and warm about brass that has aged, and a bike that wears patina with pride. The fine folks over at Blue Lug in Japan couldn't find good quality brass spacers, so they started making their own.

This tapered spacer fits the contours of our  (and probably others) perfectly, making the transition from the bearing cover smooth.

Height of 12mm.  Outer diameter at the top of the spacer is ~31.6mm.
