Wahoo Fitness BlueSC cycling sensor preview

It wasn't all that long ago that Wahoo Fitness unveiled it's iPhone 4S friendly BlueHR heart monitor to let you track your workouts. Well, it turns out that Wahoo's been working on something new, and at a Bluetooth 4.0 event today in SF, we got a sneak peek at the company's next device, the BlueSC. It's a gadget aimed at would-be Alberto Contadors that wirelessly tracks the speed and pedaling cadence of cyclists via Wahoo's existing app. It's a three piece affair with a main hub that straps to your bike frame, one magnet that goes on your wheel, and a second that's placed on the pedal crank. The hub gets rotational info from each magnet as it swings past and then shoots your stats to your phone via Bluetooth, allowing you to track your performance as you chug up the Alpe d'Huez. (OK, maybe just around the neighborhood.) What you see above is a working prototype device, but Wahoo's being coy about further hardware details, pricing and availability -- though we can say that it's quite lightweight and can't weigh more than few grams. In the meantime, you can get a better look at your next training tool in the gallery below.
