The Model A/1 Gravel 650B has been designed for the explorer within. 650B wheels with wide, knobby tires make the A/1 a very capable machine off-road. Sleeken the tires and the bike will turn into a fast, comfortable urban machine with braze-on mounts and plenty of room for racks and fenders. The 1X drivetrain is efficient and powerful, and with internal cable routing for a dropper post, no gravel road will be left undiscovered.
It’s perfect for the rider who does more riding off the beaten path than on. It is adventure riding amplified, while at the same time only a tire swap away from sleek road commuting.
LIGHTER. STRONGER. PROFOUNDLY BETTER.
VAAST Bikes are the first to use ALLITE SUPER MAGNESIUM. This high-strength alloy features excellent shock absorption properties, weighs 33% less than Aluminum and 50% less than Titanium by volume, and is significantly stronger than both. Through the exclusive use of this eco-friendly metal, VAAST Bikes have achieved a ride feel like no other.
V-Fit
VAAST Bikes redefined V-Fit parameters account for more than just fitting your body type and measurements. They create a riding posture that is more attuned to an enhanced feel, quicker reflexes and steer control, and responsive climbing ability. A more upright riding position suits the rider who isn’t hell-bent on a podium finish. Our V-Fit helps balance your physical ability to control actions in the cockpit, resulting in a more confident approach to riding different surfaces. Ultimately, combining V-Fit with the exclusive lighter, stiffer, and more shock-absorbent Super Magnesium frames delivers a remarkably comfortable fit and feel in a performance bike. The longer your body feels good, the farther you can extend your ride, and, ultimately, the more adventure you can pack into each day.
