EBB Frame Shell Modification
From Pvdwiki
The Problem
After modifying the EBB of my Zion frame to reduce weight, I will now cut the shell of the frame down to 2 3/16" from 2 3/4" to match the new width of the cam. This is a lot of heavy steel that is not being used for anything.
The Cam
The modified cam is 2.1875" wide.
The EBB Shell
The original shell. 68mm 2.677"
The shell mod complete. 42 grams off the frame.
The finished mod. 96 grams gone.
