The previous Flux model has been Fox's stalwart in the mountain bike helmet sector and is their best selling bike product of all time. The original version launched in 2006 and was arguably one of the first helmets specifically designed for MTB trail riding rather than rebranding XC racing lids that were lifted from the road market.
The new Flux features an updated look, Varizorb multi-density EPS, a flexible visor, and a 300º retention system. There are two models to choose from, the €95 Flux and the €145 Flux MIPS, which believe it or not, includes MIPS as well as a magnetic Fidlock Snap buckle.

Construction and Features
The Flux's base is constructed from Varizorb EPS foam that is injection molded from two sides with internal pyramids that help to dissipate impact energy. A structural internal cage is molded into the foam which helps with overall strength and better energy dissipation.
The visor can be adjusted to suit your tastes and is made from thin and very flexible plastic, this should help to prevent adding any rotational leverage in a crash and breaking under impact.
This plastic cage was inspired by the ProFrame helmet which has a plastic frame running from the chin bar through the EPS foam, into the main shell. It adds strength to the overall construction.
The Varizorb foam is injected from two sides and the pyramids are said to help dissipate energy in an impact.
The retention system works around 300º of the head to fit most head types and shapes. This system also has adjustment to raise and lower the retainer location at the back of the head and near the temples to further adjust the fit.
A Fidlock Snap magnetic buckle is used on the higher-tier MIPS version. These buckles are great and are being found on more and more helmets – it allows the rider to easily close the buckle using one hand even when riding along.
The liner can be removed and washed but is made from antibacterial X-Static material that should keep your head and helmet smelling fresh.
There are a total of fourteen 'Big Bore' vents that are combined with long channels which run internally along the length of the shell, connecting the vents and helping to keep the air flowing over your head.
The Flux should be available in your nearest Fox dealer from today onwards. Expect a full review in the coming months after we put the Flux to the test. Stay tuned for more new products from Bike Connection Winter, currently taking place in Massa Marittima, Italy.
