Double-butted 6061 aluminum reduces weight via carefully-varied tube wall thicknesses. Double-butting reduces mass by thinning the tube walls where extra material would just be dead weight and retaining strength where it's needed. Impressively light – just 268g for the 700mm option. Zero rise is perfect for keeping tall 29er front ends low for balanced control. Choice of three widths to fit any rider or riding style: 700mm, 760mm and 800mm. Dropping the central bulge relative to the bar's centerline creates a smooth, flat topped bar. Flat top allows precise mounting of lights and accessories. Ideal paired with a short stem. 9º backsweep allows angle adjustment by rolling the bar in the clamp.
