Bad news, road cyclists: winter's here. Eventually, most of us decide that the possible gains from staying out on the road in unforgiving winter conditions are outweighed by the discomfort of cycling in said conditions, so we move indoors for the long trainer hibernation. If you're fortunate enough to have a CycleOps Phantom 3 Indoor Cycle in the basement, this doesn't mean sacrificing your rear wheel's skewer by locking your road bike into a stationary trainer, losing use of a PowerTap rear hub by getting on a normal indoor bike, or occasionally throwing yourself into the wall during an inattentive moment on rollers. If the Phantom 3's heart is the PowerTap hub, then its brain is the Joule 2. 0 computer and its, um, liver is the included heart rate monitor. This network of data handling presents and manages all the workout metrics that you never knew you needed. Our own reviewer says of the Joule 2. 0 that it closes the gap between post ride analysis software and on the bike training. Whereas your typical computer will give you speed, average speed, cadence, distance, and even some elevation or topo information, the Joule 2. 0 gives you the information you'd normally only have when you're off the bike and in front of your computer. This includes such metrics as power data for the ride you've just completed or time periods ranging up to the last 12 months. Other information classifiable as useful and just plain fun includes the peak power setting, which clocks your power output over various lengths of time, and data about your climbing speed. The surge feature especially won us over, as it allows the rider to pinpoint exactly where in the saddle weaknesses show, and target those weaknesses in training. The Phantom also boasts compatibility with most Garmin Ant and PowerTap products to up the ante even more. The range of data collection means that, though, we've mostly focused on its winter applications as a foul weather friend, the Phantom's precise metric ...
