Specialized Flux Expert Rear Light 2017

The Specialized Flux Expert Rear Light 2017 sets a new benchmark in safety and security when riding on the road. Outputting an incredible 110 lumens, Specialized have designed this rear light, and the rest of the Flux range, to increase visibility in both bright and low-light conditions and as such, have made this visible up to 1km away in bright conditions.

Whilst a constant, steady light is good for grabbing the attention of drivers, a flash is even greater. Specialized have boosted light output by 50% whilst in Flash Mode during day time running, whilst a flip-out USB tab makes charging your high-output light easier than ever. Simply detach the Flux Expert from your bike and plug it into the wall or computer.

  • Maximum safety, even in the brightest conditions
  • 110 lumens output sets new benchmark
  • Visible up to 0.6 mile/1.0 kilometre during midday in the summer
  • Patent-pending reflector mounting system for perfect aim on 27.2, 30.9mm, and Specialized Venge seatposts
  • Ambient light sensor boosts light output by 50% while in Flash Mode during daytime running, for increased visibility
  • Integrated, flip-out USB tab to charge rechargeable Li-Ion battery in any USB port in under 90 minutes
  • All the aesthetics and performance to match the fastest road race, adventure, and commuting bikes
  • Three operating modes: Steady, 25 lumens Surge, 5-55 lumens Flash, 55-110 lumens
