Mavic offers four versions of their wireless USB-enabled computer. There is the Ultimate which has everything, the USB which has speed, the Alti which has altitude and speed, and this one, the Wintech USB HR which has heart rate and speed.
The basic features are those that hinge on speed. That means current, average, and maximum speed. Daily distance, total accumulated distance, total accumulated distance by bike (bikes #1, #2, and home trainer). "Tendency indicator" (or pace arrow), clock, stopwatch (turns on when the wheel turns on), and up to nine lap times. The heart rate features are: instant heart rate in either beats per minute or percentage of max, average heart rate, maximum heart rate, programmable work zone.
This unit shares a shape and look with the other Mavic USB computers and is distinct from their previous Wintech versions. That's because the bottom end of the computer is a USB plug. You can pop the computer out of the mount, uncover the plug, and stick it in the USB port of your PC.
Once the CPU is plugged into your computer, you can download the ride data into Mavic's own Wintech manager program. With this program you can store all your rides, see graphic representations of the rides, use it as a training calendar, and change settings on the CPU itself. All three data lines seen on the screen can be customized to your preferences. Actually, setting which data is seen where has to be done on your computer before it is set on the CPU.
Mavic bike computers use WIN wireless digital transmission at 2.4 Gigahertz, a common wireless transmission frequency. Because we know that you like to choose where you mount your wireless transmitter, we give you three choices. The fork (known as the FS), the quick release skewer lever (known as the E-Skewer) and the quick release skewer nut (known as the E-Bolt). There are reasons to choose each. The fork mount allows you to use multiple wheels, so long as all have a wheel magnet mounted on the same side and same plane as the sensor. The fork mount has a claimed weight of 14g. The E-Skewer gives you the Mavic short-throw skewer feel with a sensor mounted in it; it leaves your fork clean, but you'll need multiple skewers if you want to choose from multiple wheels quickly. It is the same shaft and nut as the Mavic BR601 (titanium shaft) and has a claimed weight of 65g (the regular BR601 is 50g). The E-Bolt allows you to use the quick-release skewer of your choice, as you simply unscrew the nut on your q.r. and replace it with this one. The E-Bolt is the choice for those who love their skewer and don't want to sully their fork with a sensor and zip ties. The E-Bolt has a claimed weight of 28g (for reference, the standard Mavic nut weighs about 10g).
The computer comes with the CPU itself, the handlebar mount, a heart rate transmitter belt, quick start guide on paper, complete user guide on CD-ROM and Mavic Wintech Manager on CD-ROM. The computer measures 70mm long by 31mm wide by 16mm thick. The handlebar mount fits on the right side of 26.0 and 31.8mm diameter handlebars (shims included). The mount can adjust so it sits flat atop your stem, above your bars, or even in front of the bars. The unit can be set so it can auto-detect two different bikes and your home trainer (rather two different wheel sensors). The CPU batteries are CR2430 and can be replaced by the user. The Wintech software works with Windows operating software. If you want cadence to register, you need to purchase a cadence sensor separately. Mavic makes both a bike-mounted cadence sensor and one that slips over your ankle, negating the need for a frame mount. There is a home trainer mount that uses a quick-lace tie so you can get the unit on and off your bike in seconds. The Mavic Wintech USB HR Computer has a claimed weight of 36g; the mount has a claimed weight of 18g.
