What sets the Lumos Ultra MIPS apart
The integrated MIPS system allows the helmet to move independently on the head during a crash, mimicking the brain's natural protective fluid. The Limeflux colourway uses a high-visibility green accent on a black shell, improving conspicuity in city traffic. The half-shell profile keeps the helmet compact and ventilated without compromising coverage.
Ideal for...
Adult urban cyclists who commute daily or ride recreationally in city environments. The MIPS technology and adjustable fit make it suitable for riders who prioritise both safety and comfort on mixed terrain, from paved bike lanes to light gravel paths.
Application of the Lumos Ultra MIPS Limeflux
Wear the helmet for city commuting, bike-to-work trips, and weekend recreational rides. Adjust the Steck Schnalle closure to achieve a snug, centred fit before each ride. The MIPS layer works passively — no additional setup or activation is required.
