The TNi AeroPocket Bike Bag is a hot dog shaped mesh aerobar bag that fits between narrow aerobars. It measures 6" X 2 3/4" X 2", large enough for 5 energy bars. The cover secures with velcro and opens from back to front. The lightweight mesh construction allows viewing of food supply levels. It is ideal for those who do not use a drinking system between their aerobars. The TNi AeroPocket Bike Bag will fit with aerobars 2 1/2" to 5 1/4" wide (inside dimensions). OneTri is one of the premier retailers for the TNi AeroPocket Bike Bag.
