Long recognized as the world’s lightest headset, the AER series offers a hybrid steel and aluminum bearing that provides even greater durability and a 35% weight savings over comparable models. Strategic machining and precision contours provide an optimal balance between weight savings and strength. The AER headset is an ideal headset choice for road and mountain bike applications- a high quality durable headset with durability and lightweight performance in mind.
AER series headsets are available at select retailers
Featuring 7000 series T-6 Aluminum cups and covers, an aluminum crown race with low friction seal, and a lightweight aluminum / steel hybrid cartidge bearing.
Strategic machining and precision contours provide an optimal balance between weight and strength, resulting in a high quality durable headset at the lightest weight possible.
For riders with an eye on weight, this hybrid aluminum /steel bearing maintains the quality and durability our bearings are known for, in a blue anodized sealed cartridge that is 35% lighter.
Take it the next level of weight savings with our AER series Interlok® spacers. Our patented Interlok spacer design provides solid interface between the top cover and spacer stack, meaning they “nest” together and into the top of the bearing cover, which helps minimize shifting under load while riding. Spacers sold separately
In 1992, we brought the Aheadset®, the original threadless headset, to market – kicking off a major change in the way bicycle frames and forks would be developed going forward.
The original design of that revolutionary headset is still found in almost all bikes on the market today.
