Pretty dirty.
Cleaned it.
Mid-cleaning process.
Used a toothbrush and simple green degreaser.
Back side, after cleaning.
Big ring, front side.
53 tooth.
Replaced with exactly the same chain-ring.
Worn teeth.
Some of the teeth are shark-fin shaped.
Quite a bit of corrosion on the aluminum...
Both old gears are "junk" but I'll keep them around.
They represent about 7 years and around 15,000 miles of riding...
