Details

A-Box Headset (IS52/28.6 l IS52/40)

AERO Integrated Cable Routing System

Fully integrated cable routing for the best Aerodynamic, swift rotation and ultra smooth shifting performance.

Frame:
IS52 / IS52, 1.5” Integrated Head Tube
ZS56 / ZS56, 1.5” Internal Head Tube

Head Tube Dimensions

The most common 1.5”-1.5” head tube standard is good enough so we don’t create a new one. Deeper upper-bearing placement not only gives more freedom to compression ring design, the extra millimeters reserved between the top cap and the upper bearing also creates a smoother cable routing.

Installed correctly, you won’t see anything on the outside, and you’ll still be able to turn the bar at least 90º in either direction. Look for BLKTEC stem and bar compatibility at first, with other brands likely to follow.
