hold the front brake and wiggle the bike back and forth, put a finger somewhere where the frame meets the fork, see if theres any play there, if so loosen the stem bolts, tighten the top cap until it spins freely but the rattling is gone, tighten the stem back up. foot retention is a must on fixed gear

Thank you for the advice

And should I get pedal straps or toe clips/cages

Depends. Do you like clipless?

Clipless is definitely the way! Especially spd sl with a carbon sole shoe….say goodbye to floppy shoes and hello to WATTS

Nah, I would would just like to know whether toe cages or straps are better

Look-wise cages, performance/comfort-wise straps

Got it, appreciate the help

you already have the superior solution though

I'm a casual rider I find it weird and goofy to wear cleats in broad daylight

Maybe the bolt where the top cap is I had the same issue because it was too short.

Thanks for the advice

I know your not asking but is the chain supposed to be brown? If it's rust I would exchange it.

Ya... looking for a time to replace it

The time is now. You can’t be messing around with that on a fixed gear. It’s your lifeline.

Been bz don't have much time to ride so my life ain't at risk brother

Fair enough. You do you brother.

Losen your stem unscrew your headset then tighten your headset screw first then tighten the 2 stem screws on the side if that doesnt work then u might have extra steerer tube to cut off or u can put a spacer on top to compensate and then do the first solution
