Wahoo RPM Cadence Sensor is rated 3.9 out of 5 by 99.
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 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 1 out of 5 by from Not consistent I have a dozen or so rides with this sensor on a road bike, zip-tied to the crank arm. The first ride was on the road and was so inconsistent. I gave it the benefit of the doubt and chalked it up to rough roads. I have a KICKR, so I was resigned to keep it for the indoor trainer. The next handful of rides were on the KICKR and it was just as inconsistent, and almost 100% lower, a lot lower. It seems the quicker you spin, the slower the sensor reads. You're better off getting the sensor that uses a magnet if you're concerned with accuracy.

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 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.

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 1 out of 5 by from Not Very Accurate I bought this a few weeks ago and attached it to the crank arm on my bike with the tie wraps and silicone case. I have done several rides but the cadence is all over the place, my averages are down and my max cadences are through the roof (my legs can't spin that fast) so it will be going back to the shop for a refund as it is unuseable....shame really
