AR: a do-it-all handlebar
  • AR: a do-it-all handlebar

    The ultimate handlebar for road, gravel, and endurance riders!


    The Coefficient AR handlebar brings a new performance factor to road and gravel riders who want the speed of the drops, and the long-ride comfort of the bar tops. The AR is the first bar to offer both, simultaneously. It’s a revolutionary handlebar. 


    From the uniquely shaped, proportionally bar tops, to the familiar hoods and drops positions, the full-carbon  AR handlebar is the first to offer riders enhanced power from any position on the bar, even late in the day on a multi-hour epic. 


    Available in 38cm, 40cm, 42cm, and 44cm, a 42cm AR weighs just 215 grams, and has been tested to the highest ISO international standards for professional road and mountain bike racing.
