STAC ZERO

Pedal Magazine - - Out In Front -

The STAC Zero is a unique trainer, be­ing one of the qui­etest, small­est and eas­i­est-to-use power-com­pat­i­ble train­ers avail­able. Us­ing a set of pow­er­ful spe­cially ar­rayed mag­nets to in­duce eddy cur­rents in the wheel rim as it passes through, the trainer cre­ates a slow­ing-down of the wheel, which you feel as re­sis­tance.

With its zero-con­tact re­sis­tance unit, there is no noise and no tire wear. The trainer it­self is com­pletely silent, which is ideal for rid­ers who live in an apart­ment with neigh­bours be­low. The only noises gen­er­ated in a train­ing ses­sion are from the bike’s driv­e­train and the rider’s suf­fer­ing. Dur­ing the test (also nap-time), my baby re­mained fast asleep.

The only down­side to this tech­nol­ogy is that it will not work with a car­bon wheel. Since the tire does not con­tact the trainer, a trainer tire is no longer re­quired. I was able to leave my cy­clocross tires on my ‘cross bike, mak­ing the tran­si­tion from in­door to out­door rid­ing a breeze. There was no need to swap tires or wheels.

Where the STAC Zero re­ally stands out is in size and weight. Without a bulky fly­wheel or re­sis­tance unit, the STAC Zero folds com­pletely flat. When stowed, the STAC Zero is only three inches tall, and can eas­ily fit into checked bag­gage or even a large back­pack as well as be ef­fort­lessly stashed un­der a bed for out-of-sight stor­age, mak­ing it a per­fect trainer op­tion for pre-race warm-ups. Weather can turn cold and nasty, es­pe­cially in cy­clocross sea­son, and the STAC Zero is the per­fect tool for those late-fall ‘cross race warm-ups un­der a tent in front of a space heater. The trainer is the light­est one tested, mak­ing it very easy to move about.

Avail­able in ba­sic or power-equipped mod­els, the power-me­ter model is both Blue­tooth- and ANT+-com­pat­i­ble, so it is able to trans­mit to a stan­dard head unit or a com­puter with such soft­ware as Train­erRoad or Zwift. The SRP is $589.99.
