Take your cycling workouts to the next level with the Sigma Rox 9.0 triple wireless cycling computer, which tracks almost every workout detail you can imagine and then displays it in graphic form on your PC. The computer is equipped with a digitally encoded three-channel wireless Sigma Transmission System (STS), which allows the computer to use several sensors at once. This simultaneous sensing means the computer can measure your pulse, track your speed, and count your cadence all without missing a beat. The STS feature allows the Rox 9.0 to maximize your training data.

The Rox 9.0's USB interface lets you transfer your training data to a PC for analysis.

The Rox 9.0's speedometer functions include options for current speed, average speed, maximum speed, and trip distance. You can also compare your current and average speed on the same screen, or check the trip distance and total distance. The computer even offers a programmable trip section counter, a roadbook that lets you create a back-and-forth itinerary.

The Rox 9.0's HR functions include ECG-precise measurements of your current, average, and maximum heart rate, along with three settable heart rate zones. Each zone has an acoustic zone alarm to notify you when you're exceeding or falling below your HR target. The display also shows your heart rate as a percentage of your maximum heart rate, along with your total calories burned and your total time in the heart rate zone.

Serious cyclists can opt to use the computer's cadence functions (current, average, and maximum), which help you ride efficiently regardless of your destination. Adding to the computer's versatility are six altitude measurement functions, nine uphill functions, and eight downhill functions. The altitude functions cover the basics (current altitude and current incline/decline) in addition to more advanced calibration functions, such as calibrating your starting altitude and calibrating via the air pressure. The uphill and downhill functions use this data to create a summation of your training session, with such tidbits as the day's total climb and descent, the day's maximum altitude, the trip distance, the rate of ascent and descent, your maximum ascent and descent speed, your average incline and decline, and your maximum incline and decline.

On top of all the other features, the Rox 9.0 includes a stopwatch, countdown timer, clock, alarm, three temperature functions, an LCD backlight, and a battery status display. The Rox 9.0 comes with a bracket for your bike handlebars and stem, and is adjustable to two wheel sizes. The computer also automatically recognizes a second bike, so you and a partner can train together using the same computer. And when you're done with your ride, the Rox 9.0's USB interface lets you transfer your training data to a Mac or PC. The information corresponds with Sigma's Data Center software, which lets you perform a comprehensive analysis of each training session. The Rox 9.0 requires a separately sold docking station to optimize the data transfer and analysis. Both on the bike and on the PC, the SIGMA ROX 9.0 answers just about all the questions you could imagine. Besides measuring altitude, inclination and temperature, the newly developed digitally encoded 3-channel wireless STS (SIGMA TRANSMISSION SYSTEM) makes it possible to use several sensors, such as pulse measurement, speed and cadence transmitter, at the same time. Using the docking station and Data Center software included in delivery, trip data can then be clearly displayed in graphic form and evaluated in detail on the PC.
