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 700c wheels and room for up to 42mm tires has been designed for riders who want the perfect blend of gravel capability without giving up anything on paved road group rides or their daily commute. The 700c wheel size is good for faster rolling speed both on and off the tarmac. And, it is just a tire swap away from exciting off-road adventuring.
