- 42T is compatible with 36T max cassettes while 40t is compatible with 34t max cassettes
- Remove the existing 17T and add the Extended Range cog without any additional spacers to create an 11-40T, or 11-42 10-speed cassette option
- Cogs come with a longer replacement B-limit screw, to avoid running the derailleur with the stock screw maxed out
