AER

AerĀ®

Long recognized as the world's lightest headset, the new AER now offers a hybrid steel and aluminum bearing that provides even greater durability and a 40% weight savings over comparable models.  Strategic machining and precision contours provide an optimal balance between weight savings and strength.  The new AER headset is now an ideal headset choice for road and mountain bike applications- a high quality durable headset with durability and lightweight performance in mind.  For a ultralight "Race Day" application, road riders can outfit their AER with a Norglide composite bearing

AER Aluminum Lightweight Bearing

The AER-Series hybrid Steel/Aluminum maintains the quality and durablility our bearings are known for, while shaving 35% of the weight.

  

 AER "RACE-DAY" Option: Norglide® Composite Bearing

 

The AER-Series "RACE-DAY" bearing option 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 (5.3g) between a layer of low-friction PTFE tape and an elastomeric rubber backing material yielding a composite bearing that weighs scant 1.5g (Road Only)
