Dial yourself in with the wired Kinetic Power computer. You get accurate power (watt) readings when you are using it with a Kinetic Trainer; all other functions are accurate on and off the trainer.
Kinetic Power Computer is an excellent cycling computer choice for use both on and off the trainer
Watt readings are calibrated based on a mathematical relationship between power and speed; together with the proprietary software you get an accurate estimate of your output
Power curve readings include power, maximum power and average power
All other functions (speed, distance, cadence, calories burned, temperature, etc.) are available and accurate during training sessions both on and off the trainer
Dual bike memory for distance, ride time and odometer; odometer reading combines mileage for Bike 1and Bike 2
Service interval reminder and low battery indicator
Includes computer, stem and handlebar mounts, speed transmitter with magnet, cadence transmitter with magnet, battery and cable ties
Power curve results are based on the "average" rider on an "outdoor ride" using the following cubic function: P = (5.244820*S + (0.01968)*S3; S = speed in miles per hour, P = power in Watts

This thing is a piece of JUNK! The zip ties that came with it were fragile at best. The wheel magnet stripped with little or no effort and would not attach. The wires for the cadence and speed sensors were not cut properly. All in all, a TOTAL FAIL!
Bottom Line No, I would not recommend this to a friend
