VAAST A/1 Allroad Super Magnesium bikes provide internal cable routing and replaceable rear axle thread plates, and are adventure-ready with fender and rack mounts.

Available in two specifications, 650B wheelset and 700C wheelset, the VAAST Model A/1 line was specifically designed to achieve lightweight ride longevity and minimal maintenance. They give the rider threaded bottom bracket cups to eliminate creak and use the leading Enduro bearings with the greatest load capacity. Practicality has been applied to design considerations like wheel axles: We use readily available standardized replacement parts to keep you moving forward in any corner of the world. We’ve optimized ride performance by incorporating the most trusted component brands in the business, like Shimano, SRAM, Stans, WTB and Maxxis into a full package that fits and feels like no other.

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.
