The bike axle and spacers can be used to set the wheel on the stand. There are two changeable PBT tips, attached to the lever by pin. http://youtu.be/hC7UQWhzCbQ http://youtu.be/JMVlE2CPfz4 13/06/12 added new version of tool. Now it's possible to use it with different sprocket sizes wheels. Unfortunately I didn't understand how to add revisions for uploaded files, that's why I just uploaded two new files and marked them "revision_1".
