You must make sure it matches the range of cogs and chain wheels you use.
Max Sprocket ?T
Min Sprocket ?T
Front Difference ?T max.
Total Capacity ?T
T is the number of teeth on cogs and chain rings.
Longer increases everthing except Min Sprocket.
It is usually better to error on the side of too long than too short.
