The A/1 2xGRX 700c offers an approachable 2x setup and a fast rolling 700c wheelset perfect for riders with a desire for a more expansive range of gears to take them where they want to go.

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.
