Flat bar with an off center 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. Built for strength with enough flex built in for all day comfort. Strong enough for All MountainFreeride, light enough for racing. Made with three different fiber types with different tensile strength and tensile modulus, including High Strength carbon fibers. Molded with an EPS mandrel inside to avoid wrinkles inside the layup during molding. All carbon fiber material is produced by Toray and uses tailor made nano Epoxy Resin for very high impact resistance. Toray is the main supplier of carbon fiber to Boeing and Airbus. 1.5K woven impact ends help prevent damage to uni directional fibers from shortening the bar or impact with the ground. The best bar for your Thomson X4 stem.
