Just would like to post on a upgrade to the nemesis axle. Upon the investigation on the nemesis steer straight I noticed that the axles had some play inside the 23mm hex adapter. So I went to ACE hardware store and bought 4 short screws and 4 washers that are just big enough to cover the O.D. of the 23mm wheel hex. This made the axle tight with the wheel hex. Will post pics later. (I did use loc- tite to keep these in place)
