Cane Creek's engineers were tasked with developing a no-compromise, best-in-class premium headset. With the 110-Series, they achieved just that -- using optimal materials, engineering the most effective internals and designing the best aesthetics available in a headset. The 110-Series offers the widest array of configurations available in a premium headset and all backed up with our new 100% Lifetime Warranty! Made from 7075 T-6 Aluminum, it is internally contoured and relieved to minimize weight and maximize strength. A captured compression ring sets the bearing preload and stays true no matter how you ride, ensuring there is no rocking or creaking. The premium split-lip sealed Hellbender stainless steel bearings provide double the protection while decreasing friction. The 110-Series is also compatible with Interlock spacers. It is hand polished and anodised, giving it a sleek and sophisticated finish.
