Скачать или смотреть Shimano Tiagra 4603 groupset

Quick video sound test.
For the past few weeks when on the turbo trainer, my bike has been noisier than usual. I bought new gear cables. I took it all apart-clean-grease-reassemble. Still noises. It does go into gear, just makes a noise while in gear. Clicking, squeaking, grinding.

I had the bike in 2013. It was given to me by someone who bought it in 2012 I think.
December 2013 I upgraded the standard groupset on the bike (52/38 13/25) to a Shimano Tiagra 4603 (50/39/30) triple as I was a heavy bodybuilder then.

Now I want a 52/36. After researching parts, found the groupset I bought off eBay is probably over 10years old now, no idea how many miles done.

So...upgrading to a new Shimano Tiagra 4700 set very soon.
