How do I know what size my sprocket is?

The sprocket size represents the first two digits in the chain designation. Example: 40A14 is size 40. The number of teeth represents the last two digits in the chain designation. Count the number of teeth.

How big is a 32 tooth sprocket?

A single chain link is 1/2" in length, or 12.7mm. So 32 links around a 32T chainring would be 12.7 x 32, a circumference of 406.4mm. But because the circumference is calculated through the center of the pin, add to that the height of a chain link, about 5mm (half for the top, half for the bottom).

How big is a 60 tooth sprocket?

Inside Diameter: 1.1245 in. Thickness: 0.086-0.092 in.

What do sprocket numbers mean?

This is the number of teeth on the driving sprocket divided by the number of teeth on the driven sprocket. For example, a front sprocket on has 20 teeth and the rear sprocket has 60, the sprocket ratio is 20/60 = 1/3 = 1:3 or 3.

How do sprocket ratios work?

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. ... For every 1 tooth that you change on the front sprocket is like changing 3 to 4 teeth on the rear (and that's true for higher gearing ratios, too).

What is an 11 32 cassette?

The rear cassette is 11 speed 11-32. This means there are 11 cogs ranging from 11 teeth up to 32 teeth (the exact cogs are 11/12/13/14/16/18/20/22/25/28/32).

What is Chainline on a bike?

Chainline is the distance between the centerline of your frame and the average centerline of your chainring(s). For 1X this is easy – If the center of your chainring teeth is 49mm from the centerline of your frame then your chainline is 49mm.

What is sprocket diameter?

The sprocket pitch diameter is an imaginary circle through which the chain pin centers move around the sprocket. The pitch diameter is the fundamental design geometry that determines the size shape and form of the sprocket teeth dimensions.

What's the best sprocket size?

A front sprocket with fewer teeth works the chain harder and robs power, as the chain has to curl more to match the smaller diameter. In general, a 14 tooth front sprocket is the smallest advisable, with 13 being used in extreme cases.

What is a hunting tooth sprocket?

Definition of hunting tooth

: a tooth in the larger of two geared wheels which makes its number of teeth prime to the number in the smaller wheel with the object of equalizing wear.

What is the pitch of a sprocket?

The teeth of the sprocket contact the surface of the bushings when the chain is wrapped around a sprocket. Pitch is the distance between the centers of two adjacent pins. Common pitches are 0.25”, known as #25, and 0.375” (#35).
