I don't think it's categoric to say it's in terrible condition and should be thrown away without measuring it and having a look at the track marks. You really need a better picture.

The uploaded resolution is 640 x 480 and I'm looking at it on a monitor that is 4k.
This is good guidance and I'd add to take the photo at higher resolution if you are going to upload it.TobinHatesYou wrote:
1) Clean as much gunk off the spindle as possible.

If you buy decent bearings they are always hardened. The best way to stop the track marks is use a bottom bracket that has been designed with a sleeve between the bearing and axle (Shimano). On 30mm axles it's usually a direct fit between the axle and bearing in which case my suggestion would be to buy bearings that are a decent fit.jlok wrote:how to avoid those track marks? softer bearings?
