Sprocket size and final drive Gearing up adds more speed and decreases the final drive ratio. You can gear down by using a larger rear sprocket or a smaller front sprocket. Gearing down reduces speed and increases the final drive ratio.
Is more teeth on a sprocket better?
The two sprockets are measured by their number of teeth. As a quick rule of thumb, the more teeth on the rear sprocket, the lower the gearing. Conversely, the fewer teeth on the countershaft sprocket, the lower the gearing.
What does less teeth on front sprocket do?
Adding teeth to the front and rear sprockets have opposite effects. Installing a larger countershaft sprocket creates higher gearing, while a larger rear sprocket lowers gearing. Similarly, a smaller front sprocket lowers the gearing while a smaller rear sprocket makes gearing higher.
How do I know my sprocket size?
Does a smaller sprocket make you go faster?
Substituting a larger front or smaller rear sprocket lowers the ratio (sometimes called taller gearing), resulting in more speed for a given engine rpm. Likewise, a smaller front or larger rear sprocket gives less speed for a given rpm (shorter gearing).
What sprocket is best for wheelies?
If your wanting to do long street wheelies, then a smaller 14t front sprocket and a little clutch dump will do the trick. IMHO , stunting slower stuff with bigger sprockets are A LOT safer than faster wheelies.
What causes sprocket wear?
Wear on the sides of sprocket teeth generally indicates improper installation of sprockets and/or shafts. If the shafts are out of parallel or not in the same plane, non-symmetrical wear will appear on sprockets or chain rollers. MAINTENANCE: After proper alignment is made, re-tighten set screws in sprocket hubs.
What size sprocket do I need BMX?
How do you count the number of teeth in a sprocket?
The easiest way to calculate sprocket ratio is to count the number of teeth on both the driving and the driven sprockets and divide the first by the second. This ratio tells you how many times the driven sprocket turns for every revolution of the driving sprocket.
How does sprocket increase torque?
Does sprocket affect speedometer?
Most new bikes have the speedo driven off the output shaft of the tranny. Changing the sprocket gearing will definitely effect both the speed indicated and miles ridden.
Should I change the front or rear sprocket?
Doing the rear is better from a chain and sprocket wear perspective. A smaller front sprocket will excert more force on the chain and wear it and the sprocket faster which is why most will tell you to do the rear. If changing front, I would recommend against more than -1.
What do sprocket numbers mean?
Sprockets vary in size according to the number of teeth they have. … The first number refers to the number of teeth on the smallest sprocket (the highest gear, for fast pedalling at speed) and the second number to the biggest sprocket (the lowest gear, for climbing hills).
What is the pitch of a sprocket?
Pitch represents the amount of pitch diameter in inches per tooth. Sprockets with a larger pitch will have bigger teeth. Common pitches are 0.25”, known as #25, and 0.375” (#35).
How do I order a sprocket?
How do I process an order on Spocket?

How do I choose a sprocket?
The sprocket size is dependent on the driver size, the riders gearing preference and riding preference. A small gearing will make it easy to accelerate but lower the top speed. A larger gearing means the bike is more difficult to pedal initially but has a greater top speed.
What will a larger rear sprocket do?
Gearing down by installing a larger rear sprocket (like with our YZ example) increases the final drive ratio and reduces top speed, but can increase acceleration. Gearing up, like with a smaller rear sprocket, decreases the final drive ratio and adds more top speed to your motorcycle or ATV.
Is a bigger sprocket faster BMX?
Big Sprocket Advantages According to Odyssey BMX, the larger a sprocket size is, the less force it exerts on a chain. Therefore, a BMX bicycle with a larger sprocket will experience less broken chains or rear cog teeth than a BMX bike with smaller gearing.
Does a bigger sprocket make wheelies easier?
Definitely can pump up some easier wheelies with sprocket change.
How do sprockets increase speed?
To increase low end power, you should increase size of rear sprocket or decrease size of front sprocket. To increase top speed, you should reduce size of rear sprocket or increase size of front sprocket.
How long do sprockets last?
A common rule is to replace both front and rear sprockets every time you replace your chain. This is a good rule to follow if your chain has lasted for its full life of, say, 15,000 miles. But, sometimes a sprocket replacement can wait in cases where you’re replacing a prematurely worn chain.
How do I know if my sprocket needs replacing?
If the teeth are sharp, the sprocket is worn. Look for indented wear around the circumference of the sprocket at and below the teeth that resembles the shape of the chain. This “shadow” wear indicates a well-worn sprocket that should be replaced.
What causes a wear on one side of a sprocket?
Wear on one side only means the sprockets are parallel, but one is off to one side. Wear on both sides indicates that the sprocket is twisted out of parallel with the other, i.e. the rear axle isn’t set correctly, one side is more forward than the other.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
