J&R Helpful Hint: Most bikes will require a 113mm length bottom bracket spindle when using these cranks. You can typically use the standard (short) chromoly or alloy chainring bolts (Profile and some stock gears will require longer chainring bolts). You will need a crank arm puller that is designed for use with a square bottom bracket.
