Profile Design DRV/GMR Road Drop Handlebar - 42cm 120mm Drop 136mm Reach 31.8mm 9mm Rise Black. Profile Design DRV/GMR road handlebars- Where most gravel bars flare the drops the DRV/GMR keeps the upper part of the drops straight with a significant flare in the lower part of the drops. This is to allow the levers to be held in the way they were designed. 9mm of rise on the tops and hoods facilitate a higher position.
