Where it fits for triathletes
The points below are our reading of the listed features, not test results.
- No cage. Magnetic mounts remove the cage, which some riders prefer on a clean-looking tri bike.
- Frame fit. The base screws to standard bottle bosses, so check your frame has them.
- Race use. Check that you can reach, release and replace it while riding before using it in a race.
