I was actually adressing Yaniel's post more than ptle's. I was just too lazy to scroll back up to his post figuring that most could follow the whole thread and not just a portion of it. Apparently I was mistaken and apologize for the confusion. SO to clarify, if they were running 53/34 or36 then thay had to be running 110 BCD (compact crank) arms as a 34 or 36 will not fit on a 130 BCD (standard crank). If they were in fact running 110 BCD cranks then they were running compact cranks and Bob's statement was untrue thus negating the whole discussion. I guess it all hinges on what you consider "compact" cranks. I consider a crank that with a 110 BCD a compact crank. You could put 39 and 53 tooth rings on these cranks so I guess then they would not be compact cranks anymore by my definition.
