Comparison
Do you need a separate bike computer if you have a GPS watch?
For most triathletes, a dedicated bike computer is worth adding once you're training with a power meter. Wrist-mounted GPS watches have smaller screens that are harder to glance at in an aerodynamic position, and most don't display multiple power-based fields as clearly as a handlebar-mounted unit.
For sprint and Olympic-distance training without a power meter, your GPS watch is sufficient. The bike computer becomes more compelling when you move to long-course training where granular pacing data across 4–6 hour rides starts to matter.
