Abstract
A protective plate for attachment to a bicycle frame for guiding a chain includes a plate body having a first side for facing laterally toward the bicycle frame, a second side for facing laterally away from the bicycle frame, a lower portion, and an upper portion. The lower portion of the first side of the plate body is structured to align with a bottom bracket of the bicycle, and a positioning abutment member is disposed on the upper portion of the first side of the support body. An upper surface of the positioning abutment member forms a positioning abutment for positioning a front derailleur to the bicycle frame. Additionally, a chain guiding abutment may be formed on the upper portion of the second side of the support body for guiding the chain as the chain shifts from a larger chainring to a smaller chainring.
