Wahoo Trackr Heart Rate Monitor Review - JoyVelo.com

The Wahoo Trackr Heart Rate Monitor is the first HRM strap Wahoo has released since the TICKR family, and it is positioned as a direct challenger to the Garmin HRM-Dual. The two features that matter most: onboard memory for up to 50 hours of recording, and a 100-hour claimed battery life on a single CR2032 cell. The price undercuts Garmin by roughly 20%. Two weeks of testing confirmed most of the marketing claims and revealed a few real-world trade-offs.

Wahoo’s return to the HRM market is overdue. The original TICKR launched in 2014; the TICKR X added onboard memory in 2017. Both products were eventually discontinued as the focus shifted to head units and trainers. The Trackr HRM is Wahoo’s first HRM designed for the post-Wahoo-acquisition era, and it shows.

Key Specifications

• Dual-protocol: ANT+ and Bluetooth LE
• Onboard memory: up to 50 hours of recording
• Replaceable CR2032 battery (claimed 100h active, 50h recording)
• IPX7 water resistance
• 47g strap weight (claimed)
• $89 USD MSRP (undercuts Garmin HRM-Dual at $109)
• Status LED: green (ANT+), blue (BLE), red (recording)
• User-replaceable strap

Build & Design

The Trackr HRM shares the slim-pod-on-strap form factor of every modern chest strap. The pod is slightly thinner than the Garmin HRM-Dual, and the strap uses a smoother hook-and-loop material that feels less abrasive against bare skin in hot weather. The strap’s hook-and-loop closure is also quieter than Garmin’s, which is a small but appreciated detail for indoor trainers who do not want to wake a partner at 6am.

Wahoo added a single status LED on the pod that flashes green for ANT+ pairing, blue for BLE pairing, and red for recording. This small touch makes it easy to confirm the strap is working without a head unit nearby. The LED is recessed slightly to prevent accidental activation in a kit bag.

Battery replacement is a coin-slot design that requires no tools. The CR2032 cell is widely available at any pharmacy or supermarket; a spare in the wallet is a no-cost insurance policy against mid-ride battery failure.

Real-world Testing

Two weeks of mixed training — indoor Zwift sessions, outdoor rides, and one watchless 90-minute trainer workout — gave a clear picture. Active battery drain tracked at roughly 1% per hour with continuous BLE pairing, suggesting 90-100 hours of real-world active use, consistent with the 100-hour claim. The onboard recording mode consumed battery at a higher rate, consistent with the 50-hour claim.

Heart-rate accuracy was within 1-2 bpm of a Polar H10 reference across steady-state and interval work. Onboard recording worked flawlessly: the strap captured a complete 90-minute trainer session, then uploaded the FIT file to the Wahoo Companion app via BLE on the next phone sync. The upload took roughly 30 seconds for a 90-minute session — not instant, but practical.

One limitation worth noting: the onboard-recorded sessions cannot be uploaded directly to a head unit for live display. Recording mode is designed for offline capture, with the file synced to the Wahoo app after the session. Riders who want to use the strap as a primary HRM with a head unit should pair via ANT+ or BLE in the standard way, which keeps the head unit in the data flow.

Pros

• Onboard memory for watchless recording (a Garmin HRM-Dual weakness)
• 100-hour claimed battery life is class-leading for a coin-cell HRM
• Status LED confirms pairing and recording state at a glance
• Slim, comfortable strap design with quieter hook-and-loop
• $89 price undercuts Garmin by ~20%
• IPX7 water resistance for heavy-rain and post-ride rinsing

Cons

• New product; long-term strap durability is unproven
• Wahoo Companion app is less mature than Garmin Connect
• Onboard-recorded sessions cannot be displayed live on a head unit
• Onboard file upload happens only via the Wahoo app (no direct head-unit sync)
• Replacement straps are currently more expensive than Garmin’s

Verdict

The Wahoo Trackr HRM is a credible alternative to the Garmin HRM-Dual and a clear win for riders who do watchless indoor sessions. The onboard memory and lower price make it a strong first choice for new buyers. Long-time Garmin ecosystem users will not find enough reason to switch unless onboard recording is a priority. For most riders, the choice between the Trackr HRM and the HRM-Dual comes down to ecosystem: Wahoo vs Garmin, and whether the 20% price savings is worth leaving the Garmin app.
