Stem Top No. 1
Stem Top No. 2
This is a way to take a simple stem cap and turn it into something really fun. When you have a minute, hanging out with friends, at the cafe whatever, tops are just fun, alone, to race battle or use as the timer for a moment of pause in the day.
Stem Tops have a solid brass body, precision machined by Paragon Machine Works. The standard tip is a stainless 3/16" bearing. these are easily replaced or upgraded if needed (Hint: ceramic hub bearings). The tip is retained with a M6 set screw. The Stem Top comes assembled and ready to go.
It is as simple as it looks, a direct replacement for the existing stem cap and bolt, this is one assembly that you can take on and off without tools.
