Full Speed Ahead Orbit CF-33

This headset is specifically designed for tapered head tubes with an upper inner diameter of 42mm and a lower inner diameter of 47mm. It is compatible with steerer tubes that taper from 1-1/8 inch at the top to 1-1/4 inch at the crown.

The IS42 designation indicates this is an 'Integrated Standard' headset with a 42mm upper bearing bore. This means the bearings drop directly into the frame's head tube without the need for additional cups, making installation straightforward if your frame is designed for this standard.

With an upper stack height of 10.3mm and a lower stack height of 1mm, this headset keeps your front end low. It is an excellent choice if you are looking to lower your handlebar position or if you have limited steerer tube length on your fork.

Yes, the Orbit CF-33 uses high-quality cartridge bearings that are designed for smooth operation and durability. While they are sealed to keep out contaminants, they can be easily accessed, cleaned, or replaced when necessary to maintain consistent steering performance.

Because this is an integrated headset, you do not need a traditional headset press to install cups. You will, however, need a crown race setter to properly seat the 33mm crown race onto your fork's steerer tube.
