Transform your iPhone into a powerful cycling computer with the Wahoo Blue SC for iPhone 5, iPhone 4S, iPod Touch (5th generation), iPad (3rd and 4th generations)! The Wahoo Blue SC is the world's first Bluetooth Smart (4.0) cycling speed/cadence sensor made for the new iPhones and iPad 3rd and 4th generation. This sensor and App combination transforms your iPhone into a powerful cycling computer. The Wahoo Blue SC connects wirelessly to your iOS device (no Wahoo Key or Bike Case required) and tracks your cycling speed, cadence, and distance through the free Wahoo Fitness App. The Wahoo Blue SC's exciting new odometer functionality tracks the lifetime distance of your bicycle and stores the data in the device. Whether you ride with or without your iPhone, as long as you have your Blue SC you will always know the total mileage of your bike. Using the free Wahoo Fitness Odometer App, you can sync all your data once in range of your iOS device and see the lifetime mileage of your bike by week, month and year. Additionally, our open API allows other popular Apps, such as Cyclemeter and Strava to work with the Wahoo Blue SC. This device works with the iPhone 5, iPhone 4S, iPod Touch (5th generation), iPad (3rd and 4th generations)Wahoo Blue SC will NOT work with the iPhone 3G, 3GS or 4 or earlier generation iPads.Not sure of your iPhone/iPad model?Need help using your Blue SC?Blue HR getting started guide
When I first heard about the Blue SC I was thrilled that there was an all in one sensor that would pair with my iPhone 5. I got a good deal for the SC thanks to Wahoo's Thanksgiving sale. Got it and began trying to install it on my Colnago Extreme Power. The chain stays on the Extreme Power and seriously beefy and the rubber band simple would not work, neither the supplied zip ties. Luckily I had longer zips to use. Due to the size of the stays I had to add a third tie to the wheel sensor arm to prevent the unit from flying about. I have Campagnolo Carbon Record Cranks and had to use so grease on the arms to get the cadence sensor on. The wheel magnet is useless on Mavic Ksyrium Bladed spokes. I used a magnet design for the spokes and thankfully the sensor read the magnet. So while I was a bit frustrated at first getting everything on and working, once I got it settled and strapped, the system works like advertised.. so thus I say get it! Even if you have funky gear, a little ingenuity will allow you to use this system.
I just replaced an ancient Cateye Micro bike computer with this Blue SC hardware. At present, I am using this product with the Cyclemeter app, which I find to be the most flexible in terms of interface customization. So far, I really like this combo. Installation was no more or less complicated than for other cyclometer/sensor installations. Wahoo provides two mounting options for the sensor pickup -- a rubber band and zip ties. At first glance, I liked the rubber band idea. It seemed secure enough. However, I got to thinking about wear and tear. Rubber tends to break down over time, especially when exposed to sun and heat. I had this vision of the rubber band breaking during a ride and failing to discover this fact until the ride was done. This convinced me to use the zip ties -- not as elegant, but I have never seen zip ties break! Setting up the app for my new sensors was a piece of cake. The iPhone detected them right away via Bluetooth and automatically took care of the pairing. However, the setup and detection process varies from app to app, so I can't comment about how this process works for anything but Cyclemeter. I noticed that the cadence reading takes awhile to catch up after I stop pedaling. Not sure if this is due to a slow refresh rate in the app, or if it's just the nature of the beast for wireless Bluetooth. That said, during the ride, the numbers seem to be accurate. I don't think this is a major concern. I am now looking at adding the protective case and extended battery options, and maybe even another sensor and case mount for my mountain bike. I Like the idea of being able to use my phone for multiple bikes.
Installs fairly quickly, although... Instructions are only available online (not included in retail packaging ... you use a QR code to take you to the instructions). Would like to have instructions include information about how to dial in the speed/distance readings so that they are accurate. My app seems to report speeds that are faster than the real speed (which is also resulting in distances being reported farther than they actually are). Hoping there are some technical docs/instructions included and available online soon. Great otherwise. Response: You can calibrate your sensors by going into the app that you are using and adjusting the wheel size. In our own Wahoo Fitness app you would do this on the sensor's pairing page. To get to that page go to workout settings -> sensors used -> select your Blue Sc and you will be presented with the original pairing page. Select "Circumference" and select your wheel size or select custom and enter your own!
