Ok, hers my plan:
beware, this is some intensely home job, Ghetto, Dangerous shit...
and if you choose to do the following, Tyler and co. cannot be held responsible if;
You are Injured, Maimed or killed in the riding or constructing of said hub.
Sell previously stated product, and the recipient is Injured, Maimed or killed in the riding or de-constructing of said hub
You are kidnapped by Midget Ninja Pirates and are taken to MidgetNinjaPiratesville and are Injured, Maimed, killed or violated...
ok,
now for the plan:
Take the hub off your wheel,
Find a bearing with the same internal diameter as a hub with a 20mm axle.
Find the outside diameter of said bearing(s)
Buy a drill bit the same diameter of above stated bearing.
Drill a big Fark off hole in your hub, Press bearing(s) into the hole.
Place in fork, and go shred!
For the good of the Nation, the world, and the entire Galaxy.
Do Not Do This!
