The A/1 GRX 700c offers a more premium 1x setup and a faster rolling 700c wheelset perfect for riders with a need for more speed across a wide range of riding and desire the benefits of the Shimano GRX600 groupset's renowned durability and clutch control.
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.
