The XLab Stealth Pocket 100 is a well-conceived aero bag for storing bars, gels, etc. that can be mounted behind the stem. It actually reduces drag caused by the stem and headset spacers with its tapered, aero design profile. Other details include a silver colored interior which makes it easier to see contents. A stretch mesh pocket in contrasting red color creates a divider for electrolyte tablets, salt tablets, cash or the flat repair kit (tube CO2 inflator tire levers etc.). Its long and low design means it can store the longest energy bars.
Non slip surfaces underneath and on front of bag grip top tube and back of stem to keep the bag in place. Extra-long front straps allow bag to be attached to bikes with cables entering the top tube behind the headset. The bag is located within easy reach while riding and there is a non slip rubber zipper pull. A one handed super-slide zipper makes quick grabs easy.
