• Good evening everyone.
    I'm assembling a 1998 Quantum Pro.
    I found the frame and the fork that belonged to two different owners.
    I would like to mount a 1 "1/8 headset thanks to a Cane Creek seat post shim that goes from 27.2 to 28.6mm.
    The problem is that I miss the bearing cap that rests above the upper steering tube bearing.
    Would any of you know how I could solve this problem?
    Thanks in advance
