By incorporating Norglide® composite bearing technology into a super-lightweight design, AER-Series II® offers more than 50% weight savings over comparable models. It’s the ultimate upgrade for cyclists with an eye on weight.

Tech: Norglide® Composite Bearing

The AER-Series II® headset incorporates Saint-Gobain Performance Plastics latest innovation in composite bearing technology: Norglide® T. A revolution in bearing technology, the T material sandwiches an aluminum base between a layer of low-friction PTFE tape and an elastomeric rubber backing material yielding a composite bearing that weighs scant 1.5g. 

Complete headsets include the top assembly with Norglide T® bearing, plus a lower assembly with AER-Series II® cup, stainless steel 110-Series bearing and a sealed alloy crown race.  All other AER-Series II® configurations are sold as top assemblies only,  to be pared with 110-Series bottoms to match today's myriad of head tube configurations.  As with all Cane Creek premium headsets, the AER-Series II® Series features state-of-the-art headset technology, designed and manufactured at the Cane Creek facility in Fletcher, NC, USA.
