This is my first bike ever assembled, I’m a total newbie.
I’ve just finished to put chain/cog and did my first try of chain tensioning. All components are new, but still I don’t understand why there’s so much noise when I pedal.
I’ve just put some lube to chain hoping it helps
Do you think there’s too much chain tension? It was noisy even when the chain was slack, hope I bought the right chain!
Looks a little tight. There should be +/- 0.5 inch vertical movement of the chain possible halfway between the sprockets.
Park tool has a great video on single speed chain replacement:
(link starts the video at the tensioning segment.)Readjust tension and see if it makes a difference. Also make sure the wheel is parallel to the frame.
1/8 in (3.2 mm) wide chains are typically used on bikes with a singlespeeds, but 3/32 in (2.4 mm) chains are used also. Compare the new and old chain width. If it's the same it's good. ('Width' here means the spacing between the inner plates.)
Did you replace the front and rear sprocket with the chain? Check the sprockets for wear, especially the rear one.
The chain was not straight: wrong rear wheel hub size for my frame!
By calculating the chainline of my crankset and the rear frame dropout I noticed it was off by 5 mm.
My frame has a weird 126mm dropout so I had to add some spacers/washers to my 120mm rear wheel so that the chainline was off by 2 mm
