Mount style depends on the priority: visibility, aerodynamics, or cockpit integration. Out-front mounts position the computer ahead of the stem for easy viewing from the riding position without looking down — the standard choice for road and gravel riders. Stem mounts sit more rearward and are more aerodynamic for time trial and triathlon setups where glance frequency is lower and position is locked in. Integrated mounts — like those built into ENVE's aero stem or the Framesandgear options machined to specific frame profiles — eliminate any compromise and produce a clean cockpit without separate clamps or adapters. Frame-specific mounts matter most on integrated cockpit systems where standard aftermarket hardware simply will not fit.
Sensors extend what a GPS head unit can track. Speed and cadence sensors add wheel speed and pedaling data to GPS-based computers, useful in areas with poor satellite reception or when paired with indoor trainers that lack built-in broadcasting. Garmin's HRM-Tri and HRM-Swim straps are designed specifically for multisport use — the Tri strap stores heart rate data during the swim when a watch cannot receive live transmission, then syncs to the head unit afterward. The HRM 600 uses an optical sensor array in a chest strap form factor, capturing heart rate without electrode pads.
