A custom version of a standard 1 1/8” Chris King sealed bearing NoThreadSet™, developed between Pegoretti and Chris King to fit the oversized head tube dimensions of our frames.

The design of the D11 uses the proven bearings and components of King’s standard models but features cups with a larger diameter skirt where they are pressed into the head tube. As the skirt is longer than the standard, it gives better support to the head tube. In addition, the shape of the cups has been modified to flow better with steel and/or titanium frames.

The D11 headset works equally well with the Falz fork and other 1-1/8” forks as the bearing sizes keep to the same dimensions as the standard NoThreadSet™. It features Chris King’s Grip-Lock fastening system as well as King’s 10-year warranty.
