Oh good job Jen ! I'm all for doing whatever works. I'm not entirely up to speed on that particular models geometry but it's obvious you'd be a candidate for a TT/Tri frame with a much steeper STA(typically 78d). Plus, shorter cranks and/or a mid-foot cleat position would definitely help you here as that is part of why you're wanting to be more forward in the first place, to place yourself in the optimal position over the BB to push down and back along the chainstays to the rear wheel. There's like a sweet spot, like an apex, where you're able to use every bit of the power you do have back to the rear wheel while your upper body is relatively relaxed. I can't help but picture the Roadrunner cartoons when the RR is at full speed from a side angle. The body is leaning forward while the trailing legs are in a blur of speed propelling the RR forward with ease. Zoom zoom zoom !
