Our favorite carbon fork compression plug for years, the Ritchey WCS Headset Compression Device is well designed, simple, effective and light weight. The pieces are machined from aluminum and work perfectly to evenly expand so that your 1⅛" carbon steerer is protected from damage. The light textured surface of the internal plug won't damage the carbon yet hold effectively when installed and adjusted properly,

One of the reasons we love this compression device is the top lip that not only prevents the device from falling into the fork steer, but also prevents over compression of the top of the carbon steerer tube while creating an even surface. Ritchey includes a headset top cap as part of the assembly. You don't have to use it, but you do need to make sure any bolt and cap you use integrate properly. Compression devices of all kinds provide an anchor for you to safely tighten down your headset for proper, free movement on the bearings. Use this Ritchey device and stop worrying.
