Arenberg: The Road Ride for All


The Arenberg Forest isn’t solely an iconic section of cobbled roadway during the famed Paris-Roubaix Classic. In the 1990s, the Arenberg maintained a rich heritage in the Litespeed road range as one of the most iconic models in our history; a true performer on the road.

And now, it’s back—reimagined for every rider, and better than ever.

Welcome to a model with the versatility of no other titanium bike at this price, poised for the road, grand fondos, even smooth gravel roads. We’ve never had a bike with this level of all-around ability at this price—until now.

While wallet-friendly, the Arenberg cuts zero corners. Engineered with a slightly less-aggressive riding position than other models in the Litespeed line, 3AL/2.5V titanium tubesets are handcrafted by our expert fabricators in Chattanooga, Tennessee using globally sourced premium materials. With uniquely updated chainstay design, clean internal cable routing* and disc brake power, you’re free to fly. Take on pitchy climbs, carve swooping descents with brilliant handling, and go for the town sprint.

With its toughness and modern tire clearance to 35mm, the Arenberg simply flies on smooth roads, broken pave with neglected chip seal, and can handle groomed dirt roads with comfortable ease. With a wide range of complimentary features like color logo or bright brushed finishes, as well as optional TiDize color anodizing upgrades—you can add a bit of personalized style to your ride.

The Arenberg will become your centerpiece ride—over any road, in all conditions. For the first time in decades, we’ve made a Litespeed road bike more attainable than ever.

*External cable routing required for mechanical builds.
