FAQ:

Q: What is a one-piece crank system?

A: One piece of steel forms the crank arms and goes from the pedal, through the bottom bracket, to the other pedal. This crank also acts as the bottom bracket bearing axle. The one-piece crank system can be replaced with a three-piece bottom bracket system using a different bearing system and a spindle that is separate from the cranks.

Q: How do I disassemble a one-piece crank?

A: To disassemble a one-piece crank, start by removing the left pedal (turn it clockwise to unscrew it–everything on the left side of a one-piece crank is left (reverse) threaded.) Then remove the locknut on the left side bottom bracket (clockwise to remove), lift off the keyed washer, and unscrew the left cone (clockwise to remove.)

Q: What size is a one piece crank shell?

A: Bicycle bottom bracket (crank hanger) shells fall, in general, into two groups, threaded and threadless. One-piece cranks fit only the unthreaded shells 51.3 mm (2.02″) in diameter. One-piece cranks are the easiest type to service, and require no special tools.

Q: What is a 3 piece bottom bracket crank?

A: This crank also acts as the bottom bracket bearing axle. The one-piece crank system can be replaced with a three-piece bottom bracket system using a different bearing system and a spindle that is separate from the cranks. The crank arm is threaded in the middle, and acts as the bottom brackets spindle.
