Introducing the pinnacle of performance and resilience - Cane Creek's AER IS42/28.6. The AER series is globally recognised for its unmatched lightweight construction and this model takes it a step further with the revolutionary hybrid bearing. This unique blend of steel and aluminium ensures durability but without the heft, offering an impressive 40% weight saving compared to similar products on the market.

The AER IS42/28.6 is perfectly suited to both lightweight road and mountain bike applications and is an ideal choice for those who prioritise both performance and weight economy. Competition is fierce on race day and every gram counts. For an even lighter race day configuration, this headset can be equipped with a Norglide® composite bearing.

The Cane Creek AER IS42/28.6 is not just about weight-saving: it's also built to last. The CNC-Machined 7075 T-6 alloy ensures that this headset maintains an optimum balance between strength and weight. Its upper stack has been expertly contoured and relieved to deliver both lightweight functionality and robust resilience.

Whether you're looking to minimise weight for racing, or seeking an economical and durable headset for your road or mountain bike, the Cane Creek AER remains a cut above the rest. Remember - every bike deserves a quality headset, because better headsets mean better rides.

Note: The upper stack measurements are 9mm (Short), and 15mm (Tall).
