Went down a massive pothole last Sunday, deep one right down to gravel. It was hidden bu puddles.
Went down with some force. Both hands left the bars and my feet unclipped. I hit my riding partner and somehow managed to keep control.
Anyway.
It didn't feel right. As if the right side was lower and slower? Seemed okay at speed, but worst when just going along.
Rode it again Wednesday and it felt the same, as if the headset was broken or a cable was pulling it off centre.
Not sure if it's all in my head?
Looked today, no cracks and all straight. The only odd mark is in the fork crown.
Is it a crack or a blob, other side is smooth as.

The other side.

You can see scuff marks and what looks like a large pin hole where the wheel has hit it.

Stick the steerer in a vice and haul it about a bit, see if it creaks or moves more than expected? Anything happened at the dropouts?

Checked over the front hub / release / axle? Might have loosend or broke with the impact.

Have the LBS check the fork dropout alignment with a Park FFG-2 or similar

Or maybe a bent axle?

Bent bars?

I could imagine a broken axle could cause the funny feeling bit, but the wheel should wobble in the forks. Are the forks carbon? I can see the steerer is alloy, but is there a carbon leg bonded on? Is that where that mark is?

The only other bit that could cause the steering to pull slightly is the headset, like you've crushed the bearings or something.

Have a thorough strip and look, and a good look at the back end as well.

I'd say your forks are knackered.

Looks like stress marks in the paint - not good.

I'd also be checking the fork alignment so too the BB alignment. If you unclipped at speed and both out you could have dislodged the BB shells and or cranks..

THose just look like rub marks. I get them from bis of stone and mud on older forks.

My approach would be systematic.

Look at your levers, are they parallel, has one slipped
Check your bars against a known straight edge
Check your stem hasn't moved left/right
Check the headset and bearings and the steerer on the fork
Check the fork (that looks fin but maybe try a straight edge again or taking them off and playing with them on a flat surface in good light
Check the wheel for loose spokes and a damaged hub

Check your arms and collarbones

Buy a new bike.
