Overview The DRV/A is a aluminum drop bar featuring a 31.8mm round diameter across the top designed specifically for clip on aerobars. The curve has been optimized for modern road levers. The innovative fit and ergonomics of the DRV system include a 7° ramp angle and a 4° flare in the drops, allowing a natural wrist angle for enhanced comfort and control. The DRiVe metric by Profile Design pinpoints the precise position in the drops where riders instinctively place their hands. The metric is incorporated into a new series of progressively sized handlebars designed around a cyclist's most powerful hand positions. What is your DRiVe?: Gone are the days of simply measuring a drop bar by the standard reach, drop and width. Our DRiVe metric pinpoints the precise position in the drops where riders instinctively place their hands. The metric is incorporated into a new series of progressively sized handlebars designed around a cyclist's most powerful hand positions. The DRiVe Metric: The DRiVe (Drop Reach Variant) position is measured via a 73° line beginning at the bar bore. The DRiVe metric pinpoints the line intersection with the drop. DRiVe Reclaims Comfort, Power & Control: Modern drop bar designs are deeply tied to tradition. They are designed based on outdated road bike sizing rendering many of cycling intended hand positions unattainable when riding modern frame geometry. The ride positions that are the most powerful and allow for the most control have now shifted into virtually unattainable positions. DRiVe reclaims many of the ideal positions most critical to comfort, power, and control.
