-before, some discomfort could appear earlier, so at the end looks like body gets stronger.
-i doubt i pull my pedals on such long climbs (i try to keep it at 80%FTP)
-mine standard (weekdays) rides are shorter - 2-3h, with 10-20min climbs.
I belive it's connected with
hip flexors (Psoas?) - I stretch them (sitting work, sitting on a bike, bad bad bad
) - maybe not enough?
that's why I ask about other muscles, which i could train/make stronger to support my body.
Yes.
Your options since you think you have a good fit
1. Stretch and strengthen
2. Lower saddle height
3. Decrease bar reach and increase bar height (reduce drop)
4. Ride more
5. Rule 5
As an aside, I have never had lower back pain in over 40 years of riding long distance. Until this year. I fractured a bunch of bone least year including the left greater trochanter (bone from femur to hip). Post accident, my left hamstring would get very painful at tempo pace and my back would be sore after a couple hours ride. It miraculously went away after a long ride in the rain. My all leather saddle developed a huge dimple where the left sit bone hits it and the leather is a bit distorted suggested an anatomical change due to the accident. Saddle looks a bit odd now. I have ridden leather saddles like Brooks B17 or Berthoud for a long time and any indentations have always been symmetrical. Whether my issue is a longer left leg or disfunctional musculature due to the accident, I do not know. But, a really top fitter might have been able to diagnose it. Just because you saw the best fitter in town doesn't mean a second opinion with someone who specializes in leg length discrepancy might not be worthwhile. YMMV
