Geiszler:~ The Geiszler is a stepped adaptor designed to work with every thru-axle fitment currently on the market: 12X142, 12X150, 15X100, 20X110 and 24 Maverick. The tool will allow precision dishing without removal, a notable time saver when wheel building. The Geiszler can be bolted into the hub with the included stud for serious wheel work. It can also be slipped into place for minor adjustments and retained by the compression of the truing stand. This simple tool eliminates clutter around your truing stand and keeps you from searching for the right adaptor.
