Product details
In use, this stem provides a more compact riding position and keeps the handlebar well-supported. CNC-machined from high-strength aluminum alloy, it is rigid and lightweight, with no play once tightened. Its handlebar clamp is at the standard 31.8 mm diameter, and it mounts on a 28.6 mm (1 1/8 inch) steerer tube. With a short length ("short reach"), it brings the handlebar closer for a more dynamic position, appreciated in mountain biking as well as on the road. The CNC finish highlights the frame, with ten colors to choose from. Important: check that your handlebar is indeed 31.8 mm and your steerer tube is 28.6 mm before ordering. Get ready for a rigid and elegant cockpit, provided you verify the diameters.
