Named after the Arenberg forest alongside the Paris-Roubaix course, the Litespeed Arenberg returns to the line with more approachable geometry and bigger tire clearance.
The frame is 3/2.5 titanium and made in their Tennessee factory. Compared to their racier bikes, the Arenberg’s head angle is ~0.5º slacker and the chainstays 5mm longer, giving it a bit more relaxed, stable ride over mixed roads. But, they say it’s still a solid climber and handler, too.
The model also adds disc brakes, and increases tire clearance to 35mm. They say it’s great for light gravel, which means it’s perfect for rough roads and dirt paths, or just all-day riding.
Cable routing remains outside the frame, but electronic shift wires and disc brake hoses run internally.
