Put Your Bars in a Choke Hold

At last month’s ABA Gator Nationals, we spied Morphine honcho Jonathan Reeves carrying a plain brown box. Under a Masonic-like vow of secrecy, he showed us what was inside. The box contained the yet-unnamed Morphine Industries pro stem, which we found most pleasing to the eye. That bit of proto product has now been dubbed the "Choke Hold." Here is the official release:

We are stoked about the release and introduction of the CHOKE HOLD stem. Its immediate impact and demand has been exciting. Morphine Industries is broadening our line of quality products this year, with many new introductions in the race and street markets. The CHOKE HOLD is only the start.
