I was very sceptic when I decided to purchase the product to be honest. Previously I was using some low-budget, Chinese bike computer with cadence sensor (cable) and it was running perfectly. Then I decided to purchase a Bluetooth kit from one of the market leading brands and... catastrophy! I couldn't even let it communicate with anyof my Android devices.Then I read some reviews of the products similar to Blue SC and I was almost sure it won't work, but I decided to give Wahoo a chance. And you know what- it is my best electronic bike accessory I've bought so far. Once it is paired with the smartphone (Huawei P9) it connects immediately as soon as you get closer to your bike and moves it.

It doesn't react as fast as cable sensors of course (due to BT response), but it is precise and reliable. I recommend it to everybody that cares about cadence and to be honest- it is one of the key features you need while biking. All the rest (distance, speed, pace, etc.) you can get even from GPS via dedicated app, but cadence (plus HR) is the key to effective training and Blue SC is the best choice!

I thought this device is great, but unfortunately it is not. Problem that I have is, the sensor give me the wrong data. Once I pedal my bike, the speed recorded was 400 kph which was really impossible. it was hard to connect to android device. after auto resting it is hard to connect again or it takes a really long time to activate the sensor again. There were several times the connection cannot be done, I don't know why, but the sensor is on, and it did not connect to another device either.I have reported it, idont know this device was really not good, or the one that I got has some defect. but I have upgraded it to the newest firmware. however they give me the great waranty. I ask to exchange to RPM Bundle sensor. I hope it will goes well. since it has not come ... MoreI thought this device is great, but unfortunately it is not.

I generally like the wahoo product line and bought this with the Tickr Fit HRM to "upgrade" my 5 year old Garmin sensors. Guess I didn't do my homework as I found the Speed/Cadence unit to be much less appealing than the more simple designed Garmin Sensors. Don't like the setup and little magnet on the spokes thing. Seems a bit of a throw-back approach? The Blue SC my work just fine, but I am still using the simple Garmins on my bike!

My old SC sensor lasted about 19-12 years. The only thing wrong was the battery compartment seal wore out allowing water inside, and it stopped working. I like Wahoo a fitness sensors and other equipment for the simple installation and setup. The price point is acceptable, too.
Out of the box, the Blue SC is easy to set up. Just follow the enclosed instructions. Remember to pair it to Wahoo Fitness app and/or the bike's head unit before strapping it on the chain stay.Once on, getting it to activate is a trial and error. The sensors need proximity - anything that's wider than half a centimetre means you lose connectivity. I had to readjust mine a couple of times before I could reliably obtain speed and cadence readings at the same time.Also, if you're using them for outdoor cycling, don't accidentally knock the Blue SC's position - you'll lose connectivity with the head unit. I discovered that after finding I had data for only half of a ride.Despite these shortcomings, the Blue SC is a neat innovation for tracking how fast and furious ... MoreOut of the box, the Blue SC is easy to set up.

It solves tracking key performance data in a neat little package.
The product works well when I've cycled using my phone to collect data, and the Wahoo app also picks up my 3rd party (TomTom) bluetooth heart rate monitor. I'm looking forward to trying the setup on Zwift at some point. Works fine & a good price.Minor issue is fitting to the bike, however with enough tie-wraps & a little gaffer tape this was fine. Will probably fit most bikes.Needed to first position the sensor on the bike frame so the sensor is ~3mm from the spoke magnet, & also somewhere near to the crank arm. After removing the pedal to put the cadence sensor on (as designed), I then needed to pack out the crank-based magnet to move it close enough to the frame-mounted sensor to work.Whether you need to do this (or can do it) depends on the shape of your ... MoreThe product works well when I've cycled using my phone to collect data, and the Wahoo app also picks up my 3rd party (TomTom) bluetooth heart rate monitor.

I recently moved to a Wahoo bike computer, absolutely love it! I bought the Blue SC to use on my vintage mtn bike (mid-90' GT Zaskar LE w/Shimano XTR, Grafton crank). I mention that only becasuse the design of bike components has changed so much over the decades. The Blue SC comes with an elastic band to hold the cadence magnet on the crank arm. Modern day crank arms big, chunky things that weigh nothing. My 26 year old Grafton crank arm is very slender and delicate looking. The elastic band for the cadence magnet is designed for the big chunky arms, not slender ones. It was impossible to get the magnet to stay in place. Imagine if a small child put on his dad's wrist watch. Or his dad's hat. THAT much too big. My solution was to cut the band, remove a section from ... MoreI recently moved to a Wahoo bike computer, absolutely love it!

Modern day crank arms big, chunky things that weigh nothing. My 26 year old Grafton crank arm is very slender and delicate looking. The elastic band for the cadence magnet is designed for the big chunky arms, not slender ones. It was impossible to get the magnet to stay in place. Imagine if a small child put on his dad's wrist watch. Or his dad's hat. THAT much too big. My solution was to cut the band, remove a section from it and zip tie the remainder to the crank arm. Then I discovered the clearance between the crank arm and the left chain stay was minimal, leaving about 0.5 mm of clearance between the magnet housing and the sensor unit mounting bands. Under a load, I suspect there will be enough frame flex that the magnet will end up touching the sensor housing.On to the positives: except for the band, install was a breeze, with two mounting options for the sensor unit: elastic band or zip ties. I'm trying the band for now, but again, the GT's slender chain stays will probably require zip ties. Next, pairing the Blue SC with my Wahoo Roam computer head unit was super easy.I called customer support about the cadence magnet issue and they were helpful, offering a workaround which could have worked but didn't. Still, I found customer support very responsive and willing to help.
Bought to replace standard Wahoo speed and cadence sensors because the Mount perished on the speed sensor (replacements all out of stock) and the cadence sensor didn’t ever properly fit on my pedal - the clearance on my Canyon is very limited. This fits better and looks. Eat but the clearance is still only just big enough. The rubber fitting of the main unit isn’t very secure and it’s fallen off once already so have had to deploy the dreaded zip tie for extra security but the sensors work well even if I seem to have to remind my Bolt they are there.
I've used a Blue SC since 2015 on my Felt road bike, and just bought a second for my new hybrid/touring bike.Follow the recommend to use zip ties to secure the sensor, and you'll have no issues. The included rubber band works, and I've used it, but there's really no reason not to use the included zip ties.I always use the Wahoo app on my iPhone for recording rides, and to Wahoo's credit, they have done a good job of supporting other services API's for uploading data.So I'll record the ride using the straightforward Wahoo app, and then post-ride upload the data (via the share button, after linking your services) to each of RideWithGPS, Strava, and MapMyRide.However, the BlueSC acts as a neutral bluetooth data source, and can be paired with any app or device that ... MoreI've used a Blue SC since 2015 on my Felt road bike, and just bought a second for my new hybrid/touring bike.Follow the recommend to use zip ties to secure the sensor, and you'll have no issues.

Just note that you can only pair it to one app at a time.So if you pair your device to eg. the RideWithGPS app, then you can't use it with Wahoo or Strava directly, without disconnecting it from that app first.Which is why I always record from Wahoo and then share out - because other apps aren't always as good for this, and the Wahoo Fitness app has no nonsense that gets in your way.Additionally, it allows you to setup multiple workout profiles and specify which sensors are relevant.So I have two Cycling profiles, one for each of my bikes, which each have their own BlueSC sensor.This way, I don't get confused or have to worry about it. I just select "Cycling: Felt" and "Start Workout" and off it goes.And my heart rate band of course is ubiquitous and is used on all profiles.So I really have no notes on the Wahoo Fitness app itself. It does everything I need it to, and that's all.If you like to record directly with another app, eg. for live logging, or if you use Cyclometer or something else self-contained like that, you can still do that.However, it is convenient to always record with the same app, so you always have all our data in one place.
Received this as a gift. With more time being spent on the rollers in the pain cave but, riding in the dark in terms of data. My wife purchased me this Speed and Cadence sensor from Wahoo. I have never owned any Wahoo devices, but have heard great things from those who have made the jump. I sighed upon opening this, telling my wife "I have Garmin, I don't think this will work be compatible." She replied. "NO! I did my research, you can set this up and use it with your Garmin". Now being more impressed with the fact my wife researched this device and its compatibility. I fell in love all over again, both with my wife and riding the rollers in the dead of winter.Set up was a piece of cake, instant data upon connection.

You can also use zip ties if needed. But I don't like the look of zip ties, plus not aero enough on the rollers.
