The Bent Up Cycles Aero Bag was designed specifically for bikes with hard shell seats and minimal rear tire clearance. Made locally in Santa Barbara, California, with quality Cordura nylon, this bag was designed by performance recumbent cyclists for performance recumbent cyclists. Get rid of the fluff - no extra straps, shock cord, webbing - just the bag! These bags also feature two of our time-tested bottle holders that allow for easy access while riding and place the bottles in an aerodynamic position behind the shoulders. Also, two small pouches attach with Velcro to the inside of the bag. Gone are the days of fishing for your keys or tire levers at the bottom of the bag! Reflective tape wraps around the bag and zipper seams are taped to be water resistant.
