Saddlebag as Buffer Zone
With most of our bicycles fitted with saddlebags, we've noticed a welcome secondary benefit: They provide an effective buffer zone. Should a bicycle fall or come into contact with an abrasive surface, the bag can protect the frame, components and saddle from getting damaged.
When a bicycle is on its side, it essentially rests on the saddlebag, without the saddle itself touching the ground. If the bag is large enough, it can even provide enough of a buffer so that the drivetrain does not suffer from impact.
