ah never mind i found my answer...
28T = 116mm
32T = 132mm
34T = 141mm
36T = 149mm
38T = 157mm
44T = 182mm
48T = 199mm

thats sick they offer different sizes of cranks and complete customization of colors etc. i think we have a winner! but still shopping and will take any reasonable advise on the way to my purchase.
