Just got back into training and I was kinda startled how much my arms have had to adapt. If you asked me after the first couple training sessions, I’d say the back of my arms is what was having to adapt a lot more than my legs or any other part of the body. When during the workout the suggestion is to “relax your arms”, well, I can curve my lower back more so the upper body kinda gets a bit more back on the bike and then I can more or less relax my arms, but either way it takes quite a bit of energy, either to keep pushing with my arms or keeping the back in a fairly unnatural position. Or, well, I can use traction of my perineum against the seat and my legs to kinda keep the upper body from falling forward, but again that’s energy that isn’t going towards producing power.
I messed around with bike geometry quite a bit already, changed out the seat post to one with a lot of offset, moved the seat back, got a short 80mm stem, played with spacers… Bike is an endurance geometry frame, Diamondback Century 6C, 56cm. I’m 5’ 11" 155lbs, long-ish inseam.
So I get it, to stay aero and to be able to put good power down, one has to accept the compromise of having some weight forward. But the question is, how does one find the sweet spot?
