The STAC Zero can be summed up as: Zero Noise. Zero Tire Wear. Through a unique arrangement of magnets interacting with your brake rim, it creates resistance while avoiding all the problems with conventional trainers. 

STAC ZERO POWERMETER 

I spend most of my time on trainers due to my busy schedule and this keeps time management of earlier workouts being more effective. I was given the opportunity to demo a new patent pending trainer that uses magnetic forces to create resistance. The STAC Zero Powermeter creates resistance to very powerful magnets on the aluminum frame of the wheel with minimal to no noise except for the drivetrain itself. The STAC Zero Powermeter pairs with all ANT+ and Bluetooth compatible apps with a wide variety of virtual trainer applications including Zwift, Trainer Road and many more. The most impressive thing is the zero noise, no contact element of the trainer.The magnetic resistance mechanism is incredibly quiet except for the noise of just the peddling and drivetrain itself. There are two versions of the STAC Zero Trainer (Base and Powermeter), I sampled the Powermeter version which has a USB rechargeable power meter with power and cadence detection. The resistance is from the magnets and the no contact with the wheel gives the cyclist no wear on the tire and no need to change to a trainer tire. This saves the athlete time, energy and of course money.  The trainer is highly compact and folds into three inches tall and only weighs around 19 pounds. This makes this compact trainer easily carried for convenient travel and/or placement in any room of your house. The seamless pairing, set up of the magnets at 12/6 o’clock and the fully assembled trainer takes about five minutes for the entire process to be virtually in any place in the world. Affordably priced for under $480. The STAC Zero Powermeter is affordable, simple to setup/pair via Bluetooth and ANT+ technology to compatible Apps with magnetic resistance that eliminates noise and reduces wear on your bike.
