With the FS2 system, BOA offers significantly finer adjustment than conventional helmet adjustment systems. The twist lock allows adjustments in both directions – in increments of less than a millimetre. This is designed to allow the helmet’s fit to be fine-tuned precisely even whilst riding. According to the manufacturer, the increments are around 40 per cent finer than with traditional systems.
A snug fit thanks to Dynamic360
At the heart of this new miracle of adaptation lies the so-called Dynamic360 system. This is made possible by a low-friction cable system that runs all the way round, designed to gently cradle the head.
Whilst traditional systems often apply pressure to specific points on the front or back of the head, the FS2 is designed to distribute the tension evenly all round. This is intended to reduce pressure peaks and keep the helmet more securely in place on the head. BOA claims up to six per cent better fit compared to conventional solutions.
A new design for a more comfortable fit
One design change involves separating the yoke (rear head support) from the headband guide. This design is intended to securely hold the back of the head in place whilst stabilising the sides. This is complemented by vertical adjustability with eleven positions, each spaced four millimetres apart. This allows the system to be better adapted to different head shapes. Conventional helmet systems usually offer adjustability in three steps.
Initial applications and availability
The FS2 system is making its debut in selected high-end helmets, including models such as the Specialized S-Works Evade 4 and the Leatt Gravity 5.0. The technology will be showcased at events including the UCI World Cup in Leogang, where visitors will also be able to try out the new fit system for themselves.

Editor's conclusion
BOA is consistently applying its tried-and-tested fastening system to helmets. The FS2 system impresses with its attention to detail: finer adjustment, better pressure distribution and a noticeably more secure fit – that is Boa’s promise. This could be a real boost to comfort and performance, particularly for demanding trail and race riders. Let’s hope the new system also eliminates old weak points, as the thin cable system has in the past sometimes caused pressure points on the sides of the head. The neck support might also be a little under-padded for sensitive wearers. We’re looking forward to the first test models.
