Why is my crank wobbling?
Chainring wobble means the chainring and the chain are moving left and right in correlation to the frame. The chain is catching sprockets at a weird angle, increasing wear on both. The riding force is unevenly transferred from the chain through the spindle to the bottom bracket bearings due to wobble.
