These are the Thomson Carbon Cross Country 31.8mm Flat Handlebars. A flat bar with an off centre clamp area allowing a flat riding position and reversible for an 8mm drop for 29 inch bikes. 6 degrees of backsweep for comfort. 730mm (29?) in width for plenty of leverage. 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. Bars are moulded with an EPS mandrel inside to avoid wrinkles inside the layup during moulding. Most other bars are moulded over inflated nylon bladders.
