So i recently bought a new piece, and it features a 29mm downstem. I plan on switching it out with this, Leisure - 18/29 mm 10 Arm Downstem - 5.0" as i know it will fit perfect. so the idea i had, is would it be possible to put a 14/18mm downstem INSIDE of the LW 10 arm downstem? so it would be: Slide --> 14/18mm downstem -> 18/29mm downstem. is this possible?
