Rear derailleur guard

A rear derailleur guard for mounting onto a bicycle having an axle, a horizontal frame member, a vertical frame member and a rear derailleur, the rear derailleur guard comprising:

• a main region having an vertex;
• a horizontal member extending forwardly from the main region, the horizontal member having an upper edge;
• a vertical member extending upwardly from the main region, forming an acute angle with the horizontal member at the apex on the main region;
• a horizontal clip on the horizontal member for engaging the horizontal frame member;
• a vertical clip on the vertical member for engaging the vertical frame member, such that when the vertical clip engages the vertical frame member and the horizontal clip engages the horizontal frame member, the axle protrudes between the horizontal member and the vertical member adjacent to the apex;
• and
• a lower shield extending downwardly and forwardly from the main region, the lower shield having an inside edge, an outside edge and exterior and interior surfaces extending therebetween, the outside edge curving to extend perpendicularly from the interior surface, so that when secured onto the bicycle the lower shield covers the derailleur and protects it from external debris.
