Take your cycling workouts to the next level with the Sigma Rox 8.0 triple wireless cycling computer, which tracks almost every workout detail you can imagine. 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 8.0 to maximize your training data.

The Rox 8.0's USB interface lets you transfer your training data to a PC for analysis.The Rox 8.0'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 8.0'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 8.0 includes a stopwatch, countdown timer, clock, alarm, three temperature functions, an LCD backlight, and a battery status display. The Rox 8.0 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 8.0'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 8.0 requires a separately sold docking station to optimize the data transfer and analysis.
The SIGMA ROX 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. PC interface available, sold separately. Features customizable display that allows the user to view ten favorite functions simultaneously while riding. Wireless speed, cadence and heart rate via encoded data transfer which eliminates cross-talk. Features 64 total functions in 12 different categories.

Customer Reviews

I just installed this yesterday, and so far I'm really impressed. The Rox 8.0 takes care of many of the annoying shortcomings found in most wireless cyclocomputers.
Installation is simple and everything is very well designed. The cadence and speed transmitters can both be installed either with zip ties or with O-rings, both of which are included. The transmitters both have green LED's that flash when they are receiving a signal from the magnet, so you know that you have installed them correctly. The batteries come pre-installed. The low-battery indicators are displayed on the head unit. The heart rate function actually worked the first time I tried it, which is rare in my experience.
The interface takes about 30 seconds of getting used to, and then it's fantastic. After your first day of using it and getting familiar with the functions, you will want to turn off the 'Button Info' feature in the settings, as this will cut your button presses in half. This feature, when turned on, displays the function of each button when you press it, and you must actually press the button a second time to perform the function. Everything is very predictable, if not fully intuitive. The bottom two buttons are used to move left and right, and as +/- buttons. The top two buttons are 'Select' and 'Back' type buttons.
The altimeter must be calibrated before each ride. You tell the Rox 8.0 your current altitude by holding the right two buttons-- this is not explained well in the manual. You can do this by retrieving one of three Home Altitudes; entering your actual altitude if you know it; or entering the current air pressure at sea level as provided by your weather station. After that, altitude is calculated using the current air pressure.
The trip values are reset by pressing the top left button. The unit stores the data from the last 7 trips if you want it to (it asks every time you reset.)
The only thing I don't like about the product is that the documentation could be better. Not all functions are explained in the manual (such as HR zone alarm, HR zone bar, how to use the alarm clock, etc.) Most of these functions are easy enough to figure out for yourself if you are familiar with similar functions elsewhere, but should still be explained in the documentation. Some are simply a mystery: I still haven't figured out the purpose of the Distance+ and Distance- functions. One counts up from zero and the other counts down from zero, and they can be reset separately from the other trip functions. I don't know why you would want to do this.

I have owned several cycling computers, including various wireless units made by Cateye and the Shimano FlightDeck. The Sigma ROX is the best I've owned yet. Setup is straightforward, and though usage takes some getting used to, once you get accustomed to the way it works it is just outstanding. It is solid, well-made. I've been caught in two heavy rain storms and this unit never stopped working and never even fogged up. The reports it produces through its PC link and software are the most detailed I have seen. I'm so happy with it that I'm looking for a second unit for my time trial bike.
