With 'the world's lightest helmet’ emblazoned across the box – and at 174g (size medium) it is noticeably light – this is clearly one for the weight weenies.
As you might expect, this leads to a pretty minimal lid. A simple but effective ratchet system is ﬁne-tuned using a dial at the back, which is easily adjusted when you’re on the move.
While the Pro 104 doesn’t feel as stable as some lids, it remains in place and the large vents work well at keeping your head cool.
If you’re unfortunate enough to crash within the ﬁrst three years you have the option of buying a half-price replacement.
