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 in front or in back for safe and dry commutes.
"The A/1 feels solid but lively. Magnesium’s damping characteristics feel closer to steel and carbon than aluminum, a sweet spot that provides decent vibration reduction and a springy, direct pedaling experience."
"The A/1’s vibration-dampening prowess through the low-frequency buzz of gravel is quickly apparent. And the frame’s low weight also shines through, with the bike finding comfortable pace quickly. And with quality components it’s a capable off-road bike that’s quite a bit of fun."
"The A / 1 with its innovative frame made of magnesium offers a successful overall package, which should be aimed at sporty touring riders due to its smoothness, seating position and equipment."
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.
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.

Our redefined V-Fit parameters account for more than just fitting your body type and measurements. They create a riding posture that is more attuned to an enhanced feel, quicker reflexes and steer control, and responsive climbing ability. A more upright riding position suits the rider who isn’t hell-bent on a podium finish. Our V-Fit helps balance your physical ability to control actions in the cockpit, resulting in a more confident approach to riding different surfaces. Ultimately, combining V-Fit with our exclusive lighter, stiffer, and more shock-absorbent Super Magnesium frames delivers a remarkably comfortable fit and feel in a performance bike. The longer your body feels good, the farther you can extend your ride, and, ultimately, the more adventure you can pack into each day.
