A: Whether it be a C110X, CT110 or NBC110 the rule is the same. The smaller the amount of teeth means more suitable for climbing (hilly areas), the more teeth allows for better top speed on flats but acceleration is a little slower.
CT110: 14T hilly areas, 15T mixed terrain standard sprocket, 16T speed, flats.
