Review of Cube’s new Heron aero helmet: A sleek shell and an all-round fit

Ventilation is provided by nine vents, including five air intakes at the front and four air outlets at the rear. Other features include the MIPS Air Node system, a triple in-mould construction and the height-adjustable SILC-180+ fit system. The helmet is available in three sizes (e.g. here) is available and, according to Cube, costs 169.95 euros.

Slim-line shell, excellent fit

With its closed top, the Heron Teamline follows the current trend towards aerodynamically optimised road cycling helmets, and its silhouette is sleek. In practice, however, it quickly becomes apparent that CUBE has not focused exclusively on aerodynamics. The helmet sits comfortably and without pressure on heads of various shapes. This means it is likely to appeal to a comparatively large target group.

The non-slip adjustment dial at the back of the helmet is a particularly welcome feature. The width can be adjusted precisely and easily, even whilst riding. In addition, the headband can be adjusted in height in incremental steps. This creates space for longer hair and allows you to wear a plait under the helmet.

Mips Air Node integrated

The MIPS Air Node system is integrated directly into the padding. As a result, it adds virtually no extra bulk and contributes very little to the helmet’s weight. Comfort remains completely unaffected in everyday use. There are no problems when wearing glasses either: the helmet shell is slightly recessed at the forehead, so that the top of the glasses does not come into contact with the helmet.

The strap routing is slightly less generous. There is comparatively little space between the front and rear straps. For riders with larger ears, the fit may therefore be a little tight. Although the manufacturer’s ‘Flat Divider’ solution is designed to ensure neat strap routing, a little more leeway would have been desirable in our test.

Good ventilation, limited reserves

Despite the largely enclosed shell, ventilation remains excellent. Air is drawn into the helmet through the front vents and channelled out the back. This works very well in normal summer temperatures, even on longer climbs. On very hot days, however, its capacity is limited. Those who frequently climb in intense heat and at low speeds will find more open road cycling helmets with even greater airflow.

Conclusion

The CUBE Heron Teamline combines an aerodynamic design with high comfort and easy size adjustment. Its balanced all-round fit, low weight of 233 grams in testing and effective ventilation make it a strong choice for training and competition. The only drawbacks are the somewhat tight strap routing and the limited ventilation capacity on very hot days. Overall, the Heron Teamline impresses with its clean finish, integrated MIPS technology and a successful balance between aerodynamic performance and everyday practicality.
