How do I know my bike chain size?
Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs. Next, measure the distance between the middle of the crank bolt to the rear axle. This is also the chain stay length.
How long do jockey wheels last?
If you clean your drivetrain often, esp after dirty rides, they will last years. I only ever replaced these on bikes I rode daily for 4 or 5 years. Once just to get some trick aluminum pulley wheels but they wore out fast.

Should jockey wheels spin freely?
REAR DERAILLEUR JOCKEY WHEELS Unfortunately, most jockey wheels are made of plastic and can wear down, making your shifting less precise than it should be. If the wheel doesn’t spin freely or grinds, your bearings could be worn down and your jockey wheels may need replacing.
Does bicycle chain make a difference?

What happens if you put a bike chain on backwards?
What happens if you put it on the wrong way? It does not impact brand new chains’ performance if you do inadvertently put the chain in the “wrong” direction. Due to wear and tear, failure to replace the chain how it was before will result in the chain and gears slipping.
Why does my chain fell off when I change gears?
Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.
