not a lot , , I twisted mine 1/3 of a turn on the first pass where I hooked with slicks , I have no idea how far it twisted to stay twisted 1/3 of a turn
Mark Williams has the Best axles , STrange Moser etc are adequate
there semm to be 100 s of gear mfgs , Richmond, Eaton, Zoom, Motive, Strange etc , all that I have used have been ok
