I am comparing a Felt DA with HED Aerobars or Oval Concepts A901's to an Argon E-114. The Argon frame alone is almost 1 lb. heavier. I THINK they both will fit me the same as in a 52 Felt DA and Small E-114, the geometry is very similar. I've heard that the E-114 is more stable, which, over an Ironman distance, adds up to less weaving and less wasted energy. I am 90% leaning towards the Argon....seems like with the available spacers for height, and very adjustable pads, I should be able to get a really good fit. Anyone have experience with either or both of these bikes? I realize the DA is very adjustable in the front with its different length stems and adjustable angle. I think from that standpoint, it may be the better choice, but I've read such good things about the E-114 (and both bikes will end up costing me about the same, with the E-114 being about $200 more than the DA for me). Just can't decide (and can't ride either bike first as no nearby dealer carries either).
