microSHIFT M55

microSHIFT M55 derailleur main image

The microSHIFT M55 has a certain style. Perhaps it is a touch derivative of a SRAM design, and the inner parallelogram plate would not be out of place on the tackiest Chinese copy of a Shimano Tourney - but these things apart, the M55 looks and feels pleasant.

Another interesting effort from microSHIFT.
