20080293528 | Independently rotating bash guard - In cycling activities, riders often encounter rough terrain having various obstacles such as rocks, mounds, tree roots, and branches. These obstacles subject the bicycle's crankset and chain to extremes in stress, loading, and impact. An improved bash guard may be attached to the bicycle to protect against damage. The bash guard may include at least one rotator operatively secured to a crankset or a crank arm on the bicycle. The rotator(s) may be configured to rotate independent of the crankset rotation. The independent rotation of the rotator(s) may permit the bash guard to roll over obstacles, significantly reducing frictional sliding or rubbing between an edge of the bash guard and the obstacles. | 11-27-2008 |
