Secure your headset with this beautifully functional new preload assembly. The Cane Creek eeTOPNUT Preload Assembly works as a compression nut in place of your traditional star nut. Use your Allen wrench to tighten it down, pressing the two cones against each other and outwards to lock your headset into your steertube with greater tension stiffness than a standard star nut. Coming in at a miniscule 9. 6 grams the eeTOPNUT saves 30 grams over the typical top and preload system.
