I have 2000 Bontrager Race Wheelset. I have been having problems with my freehub sticking and I have been trying to rebuild my hub. I have been following the instructions from the bontrager website. I have removed the axle and bearings from the wheel. I am using a 12mm hex key and try to turn it counter-clockwise to view of looking down at the drive side of the hub. Do you have any idea why I can't budge the freewheel hub or do you have any tricks to get them off?
