"I've changed the bearings in my Velomax Tempest wheels. I called Velomax and they sent me the bearings, drifts, instructions, etc. Wasn't too expensive I don't think. Don't be cheap and try to change the bearings without their specific drifts. You'll screw up the bearings."

Das Ding, mit dem der Franzose es zusammenhämmert, scheint mir so ein "drift" zu sein.
