Cannondale Reducer Headset SI/Headshok to 1.5’’-1 1/8’’ Tapered KP205Cannondale Reducer Headset Integrated Headshok to 1.5’’-1 1/8’’ Tapered KP205. In order to convert a Lefty or Headshok frame to use a standard 1.5’’-1 1/8’’ tapered fork, this is the headset kit you need. Works with SI 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, Scalpel 29, F-Si series, and some Carbon Bikes. If you have “System Integration” written on black cups pressed into the frame, this will work. However it presses into those cups and will increase the stack height. For details give us a call, or check out http://www.cannondaleanswers.com/definitive-guide-cannondale-frame-headset-fork-compatibility-for-mountain-bikes/ . Kit includes bearings, crown race, adapters, top bearing wedge, top plate, and optional stack height spacer for the bottom for increased crown clearance with certain forks.884603421857
