The peg that started the plastic craze has gotten some revisions.
Courtesy of Odysseybmx.com:
“The Pleg 2 features a completely re-designed 7075 aluminum core and proprietary plastic sleeve. This new design allows for a smaller overall peg diameter and substantially increases stiffness. The Pleg 2 core runs 3/4's of the length of the sleeve so direct damage to the core's end can be avoided, simplifying sleeve removal and maintaining socket fit. “
