Hello folks! As per the title I’m just looking for feedback on the position on my TT bike. Recently I did a 50km race pace simulation after months of build phase, mostly Z2 with a few intense efforts here and there, followed by a hard 4x8’ and a hard run session in the week and developed what seems to be a “spring knee”. Been resting, icing, and ibuprofening the past few days and it’s getting better.
I read spring knee can be caused by saddle too low and too far forward, as well as a sudden increase in intensity/volume. So, I moved the seat up and back a bit. How does this look?

Thanks all!
Does it still hurt? That would be the prime factor for me.
I had some spring knee on my road bike years ago, and I cannot remember what I did, BUT when I moved the saddle (I think for me it was actually forward but I can’t remember, unfortunately), it immediately went away and never returned. I don’t know what caused it to start (I assume the saddle being just off?), I don’t remember if I’d moved the saddle or anything before it happened, but I had gone so far as to take 3-4 days off, then it came back and I took another ~7 days off. Felt good, but it came back right away, I moved the saddle, and it never came back. ¯_(ツ)_/¯
This fit passes the eyeball test for me, at least, and I would say if it doesn’t hurt now, it’s probably good.
Full disclosure, though, I only have tinkering experience and a LOT of eyeball judging that I believe has been largely accurate, but no “training” with bike fit. Also, I’m personally not a fan of ice and/or ibuprofen… but that’s a whole other rabbit hole.
I’m measuring your knee angle at just above 150^, so the high limit of the typical fit range (145-150 with the pedal at 6:00). Given that you have had issues with the lower saddle position, I’d give this a try and see how the knee feels. You’re also not reaching with ankle flexion at BDC, so doesn’t look like you are hyperextended (just do a couple of easy sessions in this position to allow the back of your knee to adjust ).
