Ritchey Comp Mini Aero Bars. These clip-on bar extensions and pads were designed specifically for off- and on-road ultra-endurance racing and riding. The Mini Sliver features a smaller version of the original padded Sliver clip-on armrests allowing for less interference with handlebar bags and other accessories. The adjustable alloy bar extensions deliver a comfortable and aero position for successful long-distance gravel racing and pleasant extended bike touring.
