Einhaendige Bedienung des BOA Fit System Drehrads am KED Fahrradhelm

BOA® Fit System: One turn. Perfect fit.

The BOA® Fit System delivers a finely adjustable, precise fit and is engineered for uncompromising performance in the toughest conditions – guaranteed.

KED uses the BOA® Fit System in selected premium helmets, where it combines a precise fit with high wearing comfort. The head ring can be adjusted with millimetre precision using one hand, even while riding.

BOA® is part of a technology architecture in which every component has a clear task. At KED, BOA® meets the Mips® safety system, FIDLOCK® and integrated LED systems. The result is helmets in which fit, protection and ease of use work seamlessly together.

What is the BOA® Fit System?

Briefly explained

BOA® works with a central dial that precisely tightens or loosens a head ring. The adjustment is distributed evenly around the head, without pressure points. Small corrections, big effect.

Why fit is crucial

A helmet only protects reliably when it fits properly. Too loose, it slips. Too tight, it becomes uncomfortable. The BOA® Fit System helps you strike exactly this balance – quickly and precisely.

The benefits in everyday life

  • One-handed operation

    The fit can be fine-tuned with one hand, before the ride or on the go. Little effort, plenty of control.

  • Precise fine-tuning

    The BOA® Fit System responds with millimeter precision. This is especially important because head shape, hairstyle and weather can slightly change the ideal setting every day.

  • Comfort over longer periods

    Even adjustment means fewer pressure points. A helmet that doesn't pinch gets worn gladly and regularly.
