Wahoo ELEMNT Now Supports CORE, FLOWBIO, hDrop and Tymewear Sensors
Wahoo just made a serious statement about who it is tailoring its products for. Detailed support for four new physiological sensors is natively added to the ELEMNT ACE, ROAM 3, and BOLT 3, putting the data World Tour teams and PTO triathletes train with onto your screen alongside power and heart rate, i.e. core temperature, sweat loss, and breathing thresholds.
CORE went live on 2 June 2026. FLOWBIO, hDrop, and Tymewear follow in the next few days.
What each sensor does
With CORE, riders see core body temperature, skin temperature, and Heat Strain Index live on screen. I reviewed the CORE 2 and found the data interesting and actionable, though the heat training itself was hard for me to execute consistently over a training block.
The gains from sustained heat adaptation are real: increased haemoglobin mass, expanded blood plasma volume, improved VO2max. The challenge is doing the sessions, rather than understanding the data. Wahoo added a basic CORE temperature display back in 2023; the 2026 update adds the Heat Strain Index and Heat Zone data previously only in Core’s own ecosystem, making the sensor useful for guided heat training rather than just showing a number.
Tymewear’s VitalPro continuously measures breathing rate and shows the moment you cross VT1 and VT2 in real time on the bars. I tested it on and off over several months and largely trusted what it showed. The response and usefulness sit somewhere between power and heart rate, i.e. faster than HR to reflect changes in effort, but slower than power. Its value is most direct for riders whose training has been built around generic zones; breathing-based thresholds are physiologically distinct and, for some athletes, produce a meaningfully different picture of where the real limits are. For my own riding so far, the data has been interesting rather than transformative, and I hope that will change as I use it more conscientiously. Tymewear’s claim that threshold-based training delivers more than double the fitness gains of standard zones comes from their own research – plausible but, well, a manufacturer claim. At the time I reviewed the VitalPro, Wahoo support was not yet live. It is now.
FLOWBIO continuously measures fluid and sodium loss and is worn on the upper arm or clipped to a heart rate chest strap. It feeds into a hydration platform covering pre-ride planning, in-ride adjustments, and post-session recovery. Accuracy has been independently validated to a decent level, and World Tour teams use the sensor.
hDrop covers similar ground through sweat composition analysis, turning electrolyte data into hydration guidance.
I met with FLOWBIO during the prototype stages several years ago and have followed the product since then. I’ll have a crack at reviewing these two this summer.
The bigger picture: Wahoo and the sensor arms race
I recently wrote about the Coros-Wahoo partnership and noted, as I have many times before, that neither brand has a meaningful on-device third-party app ecosystem, which is a strategic weakness. On the other side of the battle, Garmin’s Connect IQ and Hammerhead’s developer tools let third parties freely add sensor support.
Wahoo already supports muscle oxygen via Train.Red and Moxy, added in 2023. That category is about to get crowded. Garmin has trademarked Muscle Battery, and Whoop has a patent on a muscle oxygen sensor. When Garmin ships branded SmO2 hardware, Wahoo may need another manual tweak to accommodate anything Garmin introduces outside the SmO2 ANT profile..
The watch question
Sources indicate Wahoo has been in discussions with Coros for over two years about Coros producing a watch under the Wahoo brand. The recently announced partnership covering data sync, treadmill integration, and hardware reselling may reflect a different preferred route, despite Wahoo’s earlier denials of considering a branded watch to succeed the Rival whihc I thought was quite good.
Prices
The update applies to all ELEMNT ACE, ROAM 3, and BOLT 3 owners. ELEMNT BOLT 3 is USD $349.99 / £299.99 / €329.99. ELEMNT ROAM 3 is USD $464.99 / £399.99 / €449.99. ELEMNT ACE is USD $499.99 / £449.99 / €479.99.
The sensors are not cheap. CORE 2 is approximately £221. Tymewear VitalPro is £299. FLOWBIO and hDrop pricing varies by region. These are tools for athletes already spending seriously on performance data, not additions to a basic setup.
Also in this update
- FIT file access via USB is back on Series 3, but must be switched on manually in the Wahoo app, and only covers rides recorded after it is enabled
- Komoot Live Sync now works on ELEMNT Series 3, pushing route updates to the head unit mid-ride without needing a Wi-Fi connection.
- The ELEMNT ACE gains a wind metrics page that uses its onboard air pressure sensor to show wind impact and an estimated wind-adjusted grade in real time — ACE only. In road testing, the estimates were interesting but not reliable enough to act on for most riders, particularly outside of solo, steady-state conditions. Wahoo is still finding the best use for the hardware.
- KICKR HEADWIND receives its first update in over eight years, adding Bluetooth support for power meters, smart trainers, CORE body temperature, and KICKR Run, with the fan responding to whichever connected sensor is driving the highest reading
FLOWBIO and hDrop are inbound for testing. For the CORE 2 review, the Tymewear VitalPro review, the Coros-Wahoo partnership analysis, and the muscle oxygen landscape, see the linked articles.
