Wahoo RPM Cadence Sensor is rated 3.988235294117647 out of 5 by 85.
Rated 1 out of 5 by from Disappointing Purchased this and installed it with the silicone cover and zip ties. It was so inconsistent (on a flat road maintaining same speed, it ranged from mid 50s to 190s, It would also disconnect from my ELEMNT and feed no data at times as well. Remounted with the double-backed tape and the connectivity issue was marginally better, but the variability didn't change. It also seems to have a significant latency problem. It is worthless in monitoring cadence, which is a significant piece of data for me. Love the concept, but this one is not ready for prime time.

Rated 1 out of 5 by from Cadence? No idea what it's telling me. I'm very happy with Wahoo products generally, but the recently installed cadence sensor (glued to my crank arm) is comically unreliable. Readings vary while my cadence is not, from 55 to 95 every few seconds. Sometimes it's pretty steady, even for miles, but then----wahoo---there it goes. So silly.

Rated 3 out of 5 by from Love the concept but looses connection I bought this to use in spin classes. I have it attached to my shoe and put my phone on the table right next to the bike (I'm the instructor). It works great when they are talking to each other but that only seems to be about 40% of the class. Often loses connection (RPM shows 0) when I am out of the saddle

Rated 4 out of 5 by from Great tool Works fine with some fluctuating numbers sometimes. Had some trouble finding a good placement on my crank arm, but it was due to the design of my crank arm. I am satisfied and can recommend the RPM cadence sensor

Rated 5 out of 5 by from Awesome Device! I bought this cadence sensor so I could step up my training and it has proved invaluable & insightful in to what I'm doing on the bike. It's allowed me to reconfig my bike to help me get the best out of my training

Rated 1 out of 5 by from Wahoo Cadence Sensor Bought this item two weeks ago and arrived with a dead battery, changed the battery 4 times now and its still running it flat over night. I'm assuming its a faulty sensor?.

Rated 1 out of 5 by from Battery Keeps Dying The sensor came with a dead battery. I asked for a new battery twice and received 0. I bought new batteries and after each ride, the battery goes dead when I go the next day. Kind of disappointing.
