When searching for the most perfectly surreal derailleur design, you might well start with SunRace’s 555 design, a seriously odd, posthumous, copy of the Shimano 600 EX (6200), naturally incorporating a bad interpretation of Shimano’s Arabesque patterning. You might then decide, as a final flourish, to prominently brand the result ‘Lepper’.
Ring that bell.
