What do sprocket numbers mean?
Sprockets vary in size according to the number of teeth they have. A cassette may therefore be sized as 11-32t. 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 plain bore?
A MPB (Minimum Plain Bore) or Pilot Hole (as it is also referred to) is a small hole drilled into a material to guide a larger drill to the appropriate location and ease the job of the larger drill, to allow for the insertion of another hole making tool such as a reamer or boring bar.
What is a pilot bore?
A pilot bore is the initial horizontal hole drilled along the intended route for the final pipe product. The main purpose of the pilot bore is to map the predetermined path of the pipe installation.

What is the difference between #40 and #41 roller chain?
#40 will be the beefiest chain in this class. This will help with thicker sprockets since there is more room between the side plates. #41 will look just like the #420 chain, but will stand shorter.
What is chain sprocket?
A chain and sprocket drive is a type of power transmission in which a roller chain engages with two or more toothed wheels or sprockets, used in engines as a drive from crankshaft to camshaft.
Is 40 and 41 chain the same?
The differences between 41 roller chain and 40 roller chain are the roller width and diameter, plate height and thickness, overall width, and tensile strength.
Is 40 and 420 chain the same?
Difference between 420 chain and 40 chain Both 420 and 40 chains have the same tensile strength and pitch, the only major difference is the width between the inner plates of #40 is larger than #420 by 1/16″.
How strong is 40 chain?
Which sprocket is faster?
A bigger rear sprocket/ smaller front sprocket will give you an increase in acceleration but decrease your top speed. A smaller rear sprocket/bigger front sprocket will reduce you acceleration but increase the top speed.
What is finish bore?
A component has a finished bore when it has a plain bore with set screws, a keyway, or both added on. Part numbering systems will frequently use an “F” or “BS” in the product number to indicate that it is a finished bore. An example of a finished bore part number would be 35BF48x1-1/4 or 35BS48 1 1/4.
What is bore in pulley?
The pulley’s bore is also known as the inside diameter, center hole, and shaft size. To collect inside diameter, simply use a ruler to measure the center hole of the pulley. Measuring the bore is unnecessary if you already know the shaft or bolt diameter.
