The F580XC by New Ultimate is one of the lightest bars on the market, at only 99 grams on the scale. Those of us who ride among densely forested areas need a narrower bar to thread a path through the dense brush. The F80XC is the ideal bar for such scenarios, with it's low weight and ergonomic sweep. At 580 mm wide and with over 200 mm to mount shifters, lockout, grips, there is sure to be enough space for everything. The carbon layup is specially tuned to provide torsional strength for when the trail in unforgiving, and is ingeniously reinforced to accommodate bar ends.
The F580XC bar is clearly printed with appropriate torque ratings for installation of the bar. The use of a torque wrench is highly recommended, as well as application of Tacx carbon assembly paste.
