Where it fits for triathletes
The points below are our reading of the listed features, not test results.
- Gravel and mixed-surface rides. Bell pitches it for road, gravel and mountain bike use, so it suits winter training on rougher routes more than draft-legal racing.
- Magnetic buckle. The Fidlock buckle closes one-handed, which is easier with cold or gloved fingers. We have not tested it.
