Magnetic Days BINARY Gear®: Revolutionizing Single Chainring Bikes

Innovation meets power in biking

Picture yourself on your bike, the wind whistling past, every turn of the wheel a symphony of precision and power. That feeling is the promise of the innovative Magnetic Days BINARY Gear® front derailleur. This isn't your typical gear shifting system; it's a revolution.

Encased within the skeleton of your bike, the BINARY® technology changes gears instantly, even under full load, straight from the bottom bracket. It's like the conductor of your bike's symphony, directing each component to work in perfect harmony. The result? An unparalleled shifting quality, maximizing the benefits of a single chainring gear, but with the potency of a double gear system.

Gone are the days of cumbersome, inefficient two-speed systems. This technology offers a wide range of ratios all from a single chainring. And with a simple flick of a switch on your handlebar, you're able to change the ratio from 1:1 to 1:1.25. It's bike tech simplicity at its finest.

More than just efficient, it's a featherweight champion in the biking world. By eliminating the front derailleur, the gear system tucks neatly into the bottom bracket's space, shedding extra weight without compromising power.

And it's as resilient as it is clever. Ensconced within the bike frame, this system shrugs off wear and tear, minimizing the vulnerability of external components. No matter how challenging your route, you can trust the BINARY® Gear system to be a reliable companion.

To put it in perspective, imagine having a calculator at your disposal that optimizes your gear use with just one click. It's a glimpse into the potential the Binary system holds for your bike. This tool is readily available online and compatible with iOS and Android devices.

They say in life you rarely get a second chance, but with the Magnetic Days BINARY Gear®, you're doubling your odds, broadening your biking possibilities.

This tech wonder is available at an enticing price, for a limited time, with an irresistible super early bird offer. But act fast! The clock is ticking, and the offer ends soon.

The open road is calling. With the Binary Gear®, your cycling experience will never be the same again. Embrace the wind, the road, and the thrill of what your bike can truly offer.
