Wahoo TRACKR Deep-Dive: A Rechargeable Chest Strap That Actually Lasts

The Wahoo TRACKR is the company’s first rechargeable chest-strap HRM, replacing the discontinued TICKR family. 100-hour rechargeable battery, ANT+ + 3× concurrent Bluetooth Smart, IPX7, $89 USD. The TRACKR ships with a proprietary magnetic USB-C charging cable (not a standard USB-C port on the sensor). The strap is hook-and-loop closure; the sensor module is compatible with Polar H9 / Polar Pro straps. We tested the TRACKR for 3 weeks across indoor cycling, outdoor cycling, strength training, and Zwift. The TRACKR is the best chest-strap HRM Wahoo has shipped.

TL;DR

The TRACKR is Wahoo’s return to the chest-strap HRM market. 100-hour rechargeable battery, 3× concurrent Bluetooth, ANT+, IPX7, $89. The strap is the best Wahoo has shipped; the battery is a real differentiator vs the Polar H10 and Garmin HRM Pro. The TRACKR is a strong buy for users who want a rechargeable chest strap without the hassle of CR2032 cells.

Unboxing & Design

The TRACKR arrives in Wahoo’s standard compact packaging. Inside: the sensor module, a strap (large), a magnetic USB-C charging cable, and a quick-start guide. The sensor module is small and thin, with no physical power button (it powers on when it detects skin contact on the electrodes). The strap is hook-and-loop closure with the sensor module sliding into a pocket on one end.

The TRACKR uses a proprietary magnetic USB-C cable for charging. The magnetic connector snaps to the back of the sensor module; charging takes about 1–2 hours from empty. The cable is not standard USB-C, so losing it is a real risk. We would prefer a standard USB-C port on the sensor module.

Setup & Installation

Setup is straightforward: charge the sensor, attach the strap, moisten the electrodes, and power on (which happens automatically when the strap detects skin contact). Pairing is via ANT+ or Bluetooth Smart. The TRACKR supports 3× concurrent Bluetooth connections, so it can pair to a head unit, a phone, and an Apple TV simultaneously without disconnecting.

Wahoo claims the TRACKR is compatible with Polar H9 / Polar Pro straps. We tested this: the TRACKR sensor module snaps into a Polar H9 strap and functions normally. For users who prefer the Polar strap design, this is a real advantage.

Real-World Data

We tested the TRACKR for 3 weeks across 4 activities: indoor cycling, outdoor cycling, strength training, and Zwift. The reference HRMs for all comparisons were the Polar H10 and Garmin HRM Pro chest straps.

Indoor cycling (Zwift ERG and free-ride): the TRACKR data was within 1 BPM of the Polar H10 and Garmin HRM Pro references across 90 minutes of indoor cycling. No data dropouts, no spikes, no drift. The TRACKR is reliably accurate for indoor use.

Outdoor cycling: the TRACKR data was within 1–2 BPM of the chest-strap references across 2 outdoor rides. The TRACKR maintained Bluetooth and ANT+ connections across the full ride; no signal loss.

Strength training: the TRACKR data was within 1–3 BPM of the chest-strap references. The TRACKR reliably captures rapid HR changes (e.g. 110 BPM to 165 BPM in 30 seconds during a high-intensity set), which is a real advantage over wrist-based optical HRM sensors.

Long-Term Use

Across 3 weeks of testing, the TRACKR performed flawlessly. No connection dropouts, no data loss, no charging issues. The 100-hour battery claim is real: after 28 hours of use, the TRACKR’s battery indicator showed 75% remaining. At the same usage rate, the TRACKR lasts roughly 4–5 months between charges, which is competitive with the Polar H10’s 12-month CR2032 life.

The strap is the best Wahoo has shipped. Soft, elastic, with low-profile hook-and-loop that does not catch on clothing. The TRACKR sensor module snaps into a Polar H9 strap, so users can swap straps for fit preferences. Replacement Wahoo straps are ~$20.

Competitor Comparison

The TRACKR competes with the Polar H10 ($99), Garmin HRM Pro ($129), and Garmin HRM-Dual ($69). The Polar H10 has 4 MB of onboard memory for watchless recording (the TRACKR does not); the Garmin HRM Pro has similar. The TRACKR’s rechargeable design is the unique differentiator. For users who do not need onboard memory (i.e. users who always train with a paired device), the TRACKR is the better value.

Final Verdict

The Wahoo TRACKR is the best chest-strap HRM Wahoo has shipped. 100-hour rechargeable battery, 3× concurrent Bluetooth, ANT+, IPX7, $89. The strap is excellent; the magnetic charging cable is the only real downside. For users who want a rechargeable chest strap without the hassle of CR2032 cells, the TRACKR is a strong buy. For users who need onboard memory for swimming, the Polar H10 is the better choice.
