Product Description

These are also called "Preload Adjustment Rings" and are part of the non-drive side/left crank arm assembly on our MR30 series cranks.  The collar threads onto the crank arm and adjusts the bearing preload of the bottom bracket.  Make sure the collar is threaded all the way onto the crank arm before installing the arm onto the spindle, otherwise you may damage your bottom bracket bearings and/or crack the collar.
