Trying to find out if a gear inch of:

Chainring: 46|42

Cog Size: 18|18

Gear Inches : 68.94|62.95

Gear Ratio: 2:56|2:33

is insane for commuting/racing (nothing fancy racing)

Chainring I am not sure I want to mess with too much, but I assume I can step down heavily and go with a smaller gear ratio (but 42t is the cap on my crank)

I am cross posting this to the CX forums as well.
