Yeah, like most things it can get bloody complicated.  Don't worry about it, start at 44:16 on 175s and see how you go, it won't be far out.

43/16=2.68

Maybe should have giving an example and got my components right :) 44 / 2.77 = 15.8 ( round up) = 16 th freewheel

for sunny day cruising round the roads on by bikes I use 16 tooth freewheel with 41/42 chainring. Nice and easy gearing if you want to roll about.
