Saiguan HG-54

Saiguan HG-54 derailleur main image

The Saiguan HD-54 is a massively constructed, largely plastic derailleur - but it looks like it means business in a Shimano Tourney Megarange kind of way. I have no evidence for or against its performance or longevity.

(I also wrote this for the Xundah YD-H75).
