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 in front or in back for safe and dry commutes. The A/1 is perfect for riders who enjoy a wide range of riding and do not want to limit themselves to one category or bike capability, keeping their options VAAST.

The Model A/1 with 650B wheels with room for up to 50mm tires was conceived for the explorer within. The 650B wheels and wide, knobby tires make the A/1 a very capable machine off-road. The 1X drivetrain is efficient and powerful and, with internal cable routing for a dropper post, no gravel road or trail will be left undiscovered. It is perfect for the rider who does more riding off the beaten path than on. It is adventure riding amplified. And, it is just a tire swap away from sleek road commuting.
