The microSHIFT rear derailleur range for 2007-2008 features:

• A range of six, closely related, mountain bike derailleurs. The range is composed of three levels of quality with two pulley cage lengths at each quality level. The basic design is an earlier version of the design of the microSHIFT M55 in this collection.
• A range of four, closely related, road derailleurs. The range is composed of two levels of quality, again with two pulley cage lengths at each quality level. In this case the basic design is an earlier version of the design of the microSHIFT Arsis (R66S) in this collection.
