MR30 Adjustable RingsThese are also called Bearing Preload Collars and are part of the non drive side left crank arm assembly on our M A R G 30 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.

Prom approved
Size: Small, Color: Black
My son got this for prom.. follow the size chart given because it is accurate. It’s very dapper and for the price way cheaper than renting something. It doesn’t look cheap at all. Very classy

Don't trust AI it lies
Size: Large, Color: Red
The AI recommended the size based on my purchases and I tell you what AI was wrong because the pants didn't fit. Everything else did not.
