Wahoo RPM Cadence Sensor is rated 4.2576 out of 5 by 66.
Rated 4 out of 5 by from Only used on indoor trainer, slow pairing I only use this sensor for RPM/Cadence on my indoor trainer with the Wahoo KICKR and TICKR. I connect with my MAC via bluetooth and ride either Trainer Road or Zwift. The cadence sensor is very accurate and I haven't needed to change the battery yet. The only downside for this sensor is the amount of time it takes to connect to Zwift and TrainerRoad. It can take anywhere from 30 seconds to 1.5 minutes to connect. 30 seconds is fine, but once I get past that I start wondering if I need to disconnect, reconnect, maybe it's out of batteries? Installation was super easy though. Pretty much set it on the crank arm and go.

Rated 5 out of 5 by from Love ditching the magnets This thing just works. It's *wonderful* to no longer have to deal with magnet alignment on cadence sensors - the bane of my existence with my bike until now. I like that it also transmits simultaneously on both BT and ANT+ meaning you can use it simultaneously with the two standards if you really need to feed your inner geek. What I wish (hint, hint Wahoo) is that Wahoo would come out with the speed sensor that does the same thing right now. Otherwise, I'm constrained to buying Garmin's sensor. I'd buy another one of these for the back wheel if they made it into a speed sensor. It ought to be the exact same hardware with only a software change.

Rated 1 out of 5 by from Dies after a few days use I use - or rather I wanted to use - this device with my Suunnto Ambit3. When I got it, it didn't work, I changed the battery and then it worked fine - but only for a week then it was dead again. within one month I have changed the battery 4 times, used it in total 8 times for 2 hours each time. Seriously disappointing!

Rated 2 out of 5 by from House Of Pain "Jump Around" If this cadence sensor had a theme tune it would be as per the title. Whilst it was easy to fit and pairs easily, sadly the cadence readings are not consistent and constantly fluctuate up and down around 5rpm on either side of my actual cadence. This has become really annoying and is driving me crazy to the point where I've gone back to using a magnet / chain stay type sensor instead. I ran them side by side for a few rides just in case it was me that had dreadful choppy cadence consistency but the readings from the magnet sensor were perfect where as the readings from the RPM did the jump around thing. I thought the unit might be faulty but my partner's RPM does exactly the same. This is such a disappointment!

Rated 4 out of 5 by from very convenient I have two of these sensors as I found it much easier to just mount them and leave them on the bikes instead of trying to use the shoe attachment method. The provided mounting options are great. One of my bikes has crank arms which are flat on the anterior side so I used the adhesive patch for a minimal clean look. My other bike's arms are concave and the adhesive wouldn't work, so I had to use the zip ties, which was quite easy as well. The only downside is the sensor is adversely affected by rough pavement and even more so by gravel trails and its accuracy suffers in those conditions.

Rated 5 out of 5 by from Sweet Just received my RPM cadence unit and have had several rides with it. The simplicity of the gizmo is elegant. It does what it is supposed to do with a simple installation, pairing with my iPhone 6sP using Abvio Cycle/Walkmeter. My cranks were not as flat on the inner face as shown in the Wahoo installation so used the silicone rubber and wire ties installation option. It seems to me that this would be a more weather tight option for those us cycling in the Pacific Northwest - it does tend to rain a bit up here. Great solution for the flexibility of cadence only for those of us using smart phones with fitness apps. The dual channel transmitter will also interface with the cycle computers I'm considering.

Rated 5 out of 5 by from Cheap, easy and effective I needed a cadence monitor that I could use with my wahoo kickr, and the rpm cadence sensor was the perfect solution. It's inexpensive, it is very easy to install and it has worked seamlessly with my trainer road workouts. I'm becoming a huge fan of the wahoo kickr, and being able to monitor my cadence during my power-focused workouts has been very helpful.

Rated 3 out of 5 by from Portability I bought the cadence sensor so that I could use it on my shoe and on different bikes. Worked great on the trainer and on a short road ride. I tried it on my shoe for 100 miles and I had shoe covers on and intermittently it didn't work, so that disappointed me. I put my iPhone in a plastic bike bag and the blue tooth worked to track me so I was disappointed the cadence sensor didn't work under shoe covers. I have not attached it to bike because I wanted to use it on several bikes.
