The Commuter strap is the smallest strap ideal for lighter objects and is the first choice for the #mainframehugger utility platform for Brompton bikes.
Note: the Commuter straps are with their max 720 mm length effectively the same length (stretched all the way) as the original Brompton shock cords, but can easily be moved to other sections of the rack and more are more secure for heavier loads.
The "flat cargo stretch straps", designed specifically for bicycles and what not, have an adjustable length, a stretch section of natual rubber, a Nylon buckle for quick opening and closing and loops at the ends of the webbing (in stead of hooks that may accidentally shoot out of your hands and end up in your eye).
Secure anything to a bicycle without scratches with these flat no hooks but adjustable loops cargo straps!
