We’ve created a specific carbon fiber flat bar with an off center clamp area allowing a flat riding position and reversible for a 5mm drop for 29 inch bikes. They also have 8° of backsweep for comfort and 730mm in width for plenty of leverage. The bars are made with three different fiber types with different tensile strength and tensile modulus, including high strength carbon fibers. This helps to allocate stiffness and flex where needed. 1.5K woven impact ends help prevent damage to unidirectional fibers from shortening the bar or impact with the ground. With a light weight and precision tolerance clamp sections, it’s the best bar for your Thomson X4 stem.
