>>1876748if you only have one chain ring it does not matter, you would only have to consider Rear sprocket sizes,
and if the chain has enough links to wrap the largest rear sprocket and largest front chain ring, then add to this 2 extra links.

28-14 rear sprocket takes up 14 teeth "aka rear difference"
26-46 Front chain rings take up 20 teeth - sometimes listed as "front difference"
if you were to use a "mega range" 14-34 tooth Rear sprocket this would use 20 teeth of the total capacity
meaning your front difference would be reduced to 14 teeth ,eg 26-40 chain rings
