Sigma Sport's Rox 8.1 is one tiny computer that packs a mighty punch! It's stuffed full of all the features you need to take your workouts to the next level, including cadence, speed, current heart rate and target HR zones, as well as temperature, altitude and ascent/descent. If that wasn't enough, the Rox 8.1 also measures current, average and maximum power using an advanced equation that incorporates bike type, rider weight, shoulder width and more. With Sigma's smart 3-channel wireless transmission system, you can view multiple measurements such as speed, cadence and pulse, at the same time without interference. And, forget about having to re-calibrate this versatile computer before every ride—Sigma's Intelligent Altitude Calibration feature does it for you!
