• Thanks for the observation. This bike is obviously not fitted and I am quite sure it will not work out with a set back seat post (slack seat tube due to mods). I don't have "knee discomfort", but "stage 3" tendinitis which the lit describes as advanced degeneration of patella tendon (already 5y with active sport phases in between). for what is worth when i ride, i do it with cleats set up in the furthest rear position and KOPS - 79.5 cm saddle height (184 cm w 86 cm inseam).
    one of the major factors of parallel inflammation of both knees for the first time was a poor fit on my second fixed gear and my ignorance of the pain (trained through the pain for weeks before eventually i couldn't even walk anymore).
