Stem Top No.2
This is the 2nd of what will be many Stem Tops. 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 Top No. 2 has a solid brass body, precision machined to our specifications 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.
System Requirements
- 1 1/8" threadless steerer
- Star fangled nut or other M6 expanding nut inside the steerer tube
- Nut needs to be in there relatively straight and 1cm or less from top of steerer (most are like this)
- Top of steerer 1mm or more below top of stem or spacer stack

The concept has been submitted to the USPTO for patent protection as a Utility Patent. That said, makers are free to use the concept for hobby use, I would love to partner with small makers and shops to do craft runs, and other possible licensing opportunities. I am easy to a fault, just drop me a note at [email protected] and if you are making these for yourself, share the pics with the tag #stemtop
