Cannondale Adapter Headshok Frame Tube to 1 1/2" / 1.5" Steerer Suspension Fork

The Cannondale Headset Headshok to 1.5 Straight Threadless can possibly help you convert Lefty or Headshok frame to use a standard 1.5 fork. This is for frames that take the Headshok headset bearing straight into the frame without the use of cups. Frames that are like this include the Rize/RZ series and some carbon bikes. If you have System Integration written on black cups pressed into the frame, this will work, but it presses into those cups increasing the stack height. Kit Includes: Two Sealed Bearings, Three 5mm headset spacers, One crown race, One conical top spacer, One top wedge, One 1.5 star nut, One 1.5 top cap, and One screw to connect to star nut.
