LUMOS Ultra Fly MIPS Helmet + Firefly LED Helmet Light Bundle

Item number: 92708

The LUMOS Ultra Fly MIPS road bike helmet in a set with the Firefly LED helmet light for more visibility and safety

The LUMOS Ultra Fly is a lightweight bicycle helmet for entry-level road cycling and is available in a bundle with the LUMOS Firefly LED helmet light. You can quickly and easily attach the light to the magnetic holder on the back of the helmet. Thanks to integrated MIPS technology, the Ultra Fly also protects your head from the rotational forces that occur in the event of a fall. It has eleven ventilation openings and can be perfectly adapted to the shape of your head thanks to the FlexiFit retention system. Your cycling goggles can be securely attached to the OptiGrip goggle port when you don't need them.
The Firefly helmet light combines three different LEDs: red, white and yellow. In combination with the Ultra Fly helmet, it is particularly the red LEDs for the rear light function the are used. Firefly is powered by a rechargeable battery and recharged via a USB cable. The battery life is up to 35 hours, depending on the light mode. Thanks to Bluetooth compatibility, you can even let the light communicate with your LUMOS helmet, your remote control or the LUMOS app on your smartphone.

In-Mold Construction
The polycarbonate outer shell is glued to the EPS inner shell, which increases the resistance of the helmet. It also makes it easier to shape vents, which means that In-Mold designs typically have better ventilation systems and a lighter weight.

MIPS (Multi-Directional Impact Protection System) is a unique technology that protects the brain in the event of an oblique impact. The principle of the natural low-friction layer of the brain is adapted in order to minimise the forces that occur.
