Where it fits for triathletes
The points below are our reading of the listed figures, not test results.
- Dark-morning rides. The 700-lumen Middle mode runs for 3 hours, which covers a typical winter long ride, and the 400-lumen Low mode for 5 hours.
- Turbo-free winter training. The 1,700-lumen mode lasts 1.25 hours by the listing, so treat it as a boost for descents and unlit lanes, not a default.
- Weather. IPX4 means splash resistance. It is not rated for immersion.
- Price. At £109.99 it is £30.00 below the RRP.
