I’ve got both and subjectively (n=1, + rides seem to confirm) that the A2 for me is slightly faster, but it is hotter.
I use the evade for training, and Olympic races and races where it will be warm/hot. Other races I use the A2. The A2 is also quieter so I get to “enjoy” the silence more. For IM Wales that is aropund the corner, I’ll bring both, but if the weather is anything like typical Welch wetaher (cold, wet and windy) , it’ll be the A2 that goes into transition whilst the evade get’s to sit it out on the sidelines…
