I've asked about drive train noise several times before..
There was also a ticking noise from the headset,
I entrusted it to nsm bike in Bucheon, which is known for its good repairs, and had everything disassembled and repaired.
The hydraulic line was in terrible condition, so I replaced all the hydraulic hoses..
The infamous s5 headset was also suspicious, so..
I replaced everything, cleaned it, and now there's no noise at all. It runs so smoothly.
Since the oil and hoses are new, the brakes feel great too ㅋㅋㅋ
Now I can finally enjoy riding my bike.
It feels like a brand new bike, and it's exhilarating.
I don't have much time to ride because I commute a lot,
and I mostly use it for commuting.. but I'll have to go for a ride soon.
It runs so well and smoothly, it feels great. My heart is light! Haha..
