Cygolite has bumped up their TridenX light from 650 to 750 lumens. The system weighs in at 290g with battery and handlebar bracket, but the light head is around 140g making it light enough for helmet use. It also includes an extension cable to run the battery in a pack or pocket.
Specs and more pics after the break…
The TridenX let’s you change the presets from the buttons on the unit, and I watched it done, took just about 20 seconds.
