The new 9 boasts a comprehensive library of well-curated profiles within each sport—for instance if a runner is on trails, the track, racing, running with power, etc. The touchscreen is predictable, and a smartphone-free setup will get you out the door quickly. The battery life is not only crazy long-lasting, but intelligently changes modes based on remaining charge. Note that the 9 does work with cycling power, but it doesn’t yet boast a full menu of pedaling dynamics.
