For the 2017 model year microSHIFT introduced mountain bike derailleurs that could handle 'one by' clusters that had maximum sprockets of 42T. In all there were five new derailleurs:

• microSHIFT XCD (M78L) - a top end model claimed to be able to handle a maximum sprocket of 42T. In 2016 a seemingly similar model, also called microSHIFT XCD (M78L), had a claimed maximum sprocket of 40T

• microSHIFT XLE 11 (M62L) - a mid range model able to handle a maximum sprocket of 42T

• microSHIFT M22L - a very basic model with a long cage
• microSHIFT M22S - a very basic model with a short cage

• and last but not least, the microSHIFT Centos (R55S) - a ten speed Centos model restyled to match the microSHIFT Arsis 11 and microSHIFT Centos 11
