The Wahoo RPM Cycling Cadence Sensor is an excellent option for cyclists who want to track their cadence and speed effectively, whether they're riding outdoors or on stationary bikes. One of its standout features is the dual-band technology, which allows it to connect seamlessly with a variety of devices including smartphones and bike computers via both Bluetooth and ANT+.

However, there are some drawbacks to consider. With a battery life of only 8 hours, frequent users may find the need to recharge it more often than they would like, especially during longer rides or training sessions. Durability is also an area to keep in mind; while it has an IPX7 rating, which means it's water-resistant, users should be cautious in extreme weather conditions. Additionally, while the accuracy is generally good, some casual users might notice discrepancies when comparing data with more advanced sensors.

While it’s compatible with many devices, some users may find it limited if they own non-Garmin products, as not all bikes or app systems may support ANT+ technology. Additionally, while the sensor is durable, it is essential to handle it carefully, as it might not be as rugged as other bike accessories designed for rougher conditions.
