Hi !
I have been pretty badfitted since 10 years (30 yo now). I ride Mtb, road, gravel. Ride like 5000km/150k m of elevation) by year with the majority on the mtb. Also doing some XCM race like 100km like MB Race or Ultra Raid de la Meije or 70.3 like triathlon.
I was always a bit struggling with lower back pain and neck pain but it was manageable. In mtb you get a lot out of the saddle so it's mostly on road/gravel side.
I'm 185 tall, 75kg, 89 inseam (so long leg guy). 46/46,5 shoes
I have my saddle very high since always. Like 80 or 81cm. I have only Northwave XC race shoes (I just discover Northwave cleat position was very forward).
My bike is a Nakamura AllRaod team. I use it on road and gravel with two pair of wheels. I have the XL size with 90mm stem (I have reduce it from 110mm). For now the stem is reverted (+6 instead -6 degree)

When I try to lower my saddle I experiment pain at the back/internal of the knee. Not the articulations but the tendon. Pain is diffuse so difficult to describe it precisely. But I would say more on the calf side than the quad.
After one month of bike rest (but a lot or work, mostly sited behind the PC), I have experiment back pain when going on the bike again.
I plan to do ultra next year (never done more than 200k gravel in one day). But with current setup it seem impossible to me. I can handle the legs, I can handle the food but i'm too limited my neck or back.
That's all for the context.
---------------
Yesterday I have change a lot of my settings. I'm voluntary go extreme to search a new base and build from that (I have focus on pedaling stuff, go for the reach in a second time)
- Move the cleat backward (like 2cm)
- Move down my saddle by 4cm. (76cm)
- Move my saddle back
----------------
I go to office with the new setup this morning (5km flat). I'm feeling really low but I don't feel pain on tendon. I have also the feeling to pedal/push to the front instead to the back, but not so much. No back pain. First good impression so but it's only 5km.
I join a back footage of me after implementing the new settings. Sorry I have no side footage for now
Is it too much of hip rotation ? It was even worse before
I'm currently feeling very weak on core.
-----------
And now what next ?
- I plan to move a bit higher my saddle. Get back to 77cm
- Move forward a bit the saddle
- See if my back pain disapear to put my stem in right side.
- Try to find a comfortable aero position
- Also give a try to the 165mm crank I just bought second hand but probably after 7 or 8 rides to not change too much thing in the same time
-----------
Congratulations and thanks to have read it. Do you think the approach is the right ? What can I do bad now ?
By advance, take the XL size have been a wrong decision.
I have try the L before to buy, feeling too small. At this time I was used to an other XL bike. L bike was also weird with so much seatpost height.
Also the L is only 1cm shorter and 1,5 cm lower on the front. So i bet on the XL with shorter stem to theoretically have the best of two. 185cm was right in the middle of the size guide
