More Aerodynamic

• Actually reduces drag caused by stem and headset spacers.
• Same width as head tube (Standard size bag), therefore no increase in frontal area.
• 72 degree front fits tight up against stem.
• Tapered aero design profile.
• Super smooth low skin friction exterior reduces drag.

Non Sway Design

• Non slip surfaces underneath and on front of bag grip top tube and back of stem.
• Direct mount into integrated top tube bolt bosses with reliable non-seizing steel screws, and sturdy plastic insert.
