>>1993711>Cheap pannier racks are pointless and will sheer off at the bolts the moment you put any load on them and hit a bumpNo one is forcing you to overload your rear rack to the point of catastrophic failure. Solutions like pick related are aerodynamic and give you storage space that doesn't wobble and flap around. If you stay within the weight limit (usually 25kg/55lbs), they'll never break. And even if you were extremely paranoid and only used 50% of that, you'd still have a very practical option for extra space on your bike.
