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 an ultralight “Race Day” application, road riders can outfit their AER with a Norglide composite bearing.
