I have this bike. And also the specialized era trispoke. Notes:
-if this fits you as a long and low frame (and you haven’t stacked it to death), that’s more than an insignificant win right there.
-I think you’ll find the combination of the Trispoke/h3 with ss20 and latex, and a rear disk cover with latex and 5000s (or a 23 ss) is a very very fast combo that still hits heavy. See this thread and links.

-reportedly, the fork and brake combo you have does test fast, despite that brake noodle and cable flapping around in the wind. Like, as fast as a good aero fork and Tririg brake. However, I long replaced the original on mine, and use a deeeeeeep Blackwell fork (that apparently pairs well with the h3) and Omega brake. This might be something to play with -maybe a deep bladed fork like the old QR carbonaero, or the cervelo wolf tt, would work, and let you run the 404 in a pinch.
-I think you could benefit from better /faster bars. Everyone likes the Tririg. Maybe the PD aeria? this, and the PD aeria stem would let you add the Aeria HF bottle and have a very very slippery superbike front end. Or, get the Tririg bar, and add that tririg nosecone for a superbike front end (I have the latter of these sitting on my workbench as my summer project).
-mine tests fastest with 1 BTS cage and 1 BTA. Your mileage may vary.

Thanks for the ideas. I'll take a look at those aero bars.
