16:32I Turned My Road Bike Into An Ultralight Hill Climb Bike With AliExpress Parts
The reviewer purchased custom aluminum ultra-light lockrings for both brake rotors and the cassette from AliExpress, curious about weight savings and quality. He compared weights: brake rotor lockrings saved 4.4g each (8.2g to 3.8g), and the cassette lockring saved 1.8g (5.4g to 3.6g). He noted these small savings add up.
