  Do you mean the axle of the pedal itself?
  
  Or of the thread dimensions of that pedal?
  
  Or the crank arm length?

  Let me answer my own questions.
  
  Axle dimension on the pedal, depends on the manufacturer of the pedal. I believe the pedals that TT uses are pretty generic and are measured in Chinese.
  
  Thread dimensions of the pedal, likely 9/16 x 20tpi.
  
  Crank arm length, likely 170mm, but some models in the TT line differ. See the specs for your model.

  I needed to know the thread dimensions. I think it's 9/16 but not sure

  If you have a bolt thru both of the crankarms and the big ring, it's a two piece crank.
  
  I've not seen any bike, or trike, with two piece cranks that use anything else other than 9/16 x 20 threads.

  9/16, at least on the Rover default hardware.

  All non-single piece cranks; their pedal thread size is 9/16 x 20. All single one piece cranks, i.e. "ashtabula" are 1/2 x 20 thread size. In BOTH sizes the rt hand pedals has right hand threads; the left hand pedal is left hand threaded. "Right and Left' are as on is sitting on the bike not looking at it from the front. Hope this helps.
