The A/1 Rival 650b offers a more premium 1x setup and a beefy 650b wheelset perfect for riders looking for added comfort and control on more technical surfaces and desire the benefits of the  SRAM Rival groupset's renowned smoothness.

The Allroad Model A/1 embodies the true notion of a more capable all roads bike. Designed for gravel, dirt, pavement, mud, and all other types of adventure “roads.” Everything has been intelligently considered and incorporated into an adventure machine you will not want to stop riding: weight reduction, more durable componentry, variable wheel size compliance, corrosion-proof inner and outer tube coating, and, most importantly, redefined superior fit and feel. These advantages have been carefully engineered into one bike to provide for a ride feel that will drive you to roam farther across every terrain.

The geometry of the A/1 enables the bike to be both a comfortable gravel grinder and an efficient and fast grand tourer. Well-placed braze-on mounts make it easy to add on racks and fenders on the front or back for safe and dry commutes.

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.
