The Fassa is our fully custom magnesium road bike designed specifically to meet the needs of the big & tall rider. We use extra beefy ovalized tubes and Lennard Zinn’s unique compact frame design to provide a bike that will perform and hold up for even the biggest guys. The Fassa is also designed for Zinn custom cranks to provide the best fit and performance on the market.

When you buy a Zinn bicycle, you expect that legendary Zinn performance combining stability and nimbleness with a perfect custom fit. What will surprise you about our magnesium bikes is their incredibly smooth, forgiving, comfortable ride, even on rough asphalt or dirt roads. Yet the torsional and lateral stiffness and low weight of our oversized and elegantly-shaped tubes means that the bike leaps forward with your every pedal stroke.

Magnesium is 2/3 the weight per unit volume of aluminum, less than half that of titanium and under a quarter that of steel. The AZ61 (Mg-6Al-1Zn) magnesium alloy we use combines low density with high strength and superb vibration-damping characteristics. That means, when mated with the Z-Pro full-carbon fork Lennard Zinn co-developed with Alpha Q, you get a comfortable, responsive, and long-lasting machine. It’s beauty and perfect fit to your body round it out to make the perfect bike.
