Will do chainline diagnostic with measurements tomorrow.
Until then, why do I have no pad-rub when freewheeling but when on the cranks its like the wheels being pulled across the stays.

Wheel likes going backwards, not forwards fail.
Draggy Sadness.

Man, you seem stressed

A good tug should see you right

(or else your frame is very flexy)
(or else there’s a crack)
(or you’re Andre Greipel)

(I’m retracting my idea up there ^ – I can’t really see how it could need a chaintug if it rubs on power but then runs freely after that)

On one chaintug turned to cheese.

Buying Surly one. Slot Dropout Inbred is the culprit.
