I was told I need a 16 point socket for the lock ring on the front sprocket but I see there are different sizes. I have the Rize RX. Which size do I need? I know I need a chain whip to remove the rear cassette but there's a lock ring on that too and there are different sizes. Can someone tell m which sizes of these I need to order?.. I don't need to take anything apart right now but the time will come.
