STEPS TO REMOVE AN AIR RESISTER:
1. Using one of the pair of trainers, remove the cable end tab; unscrew and remove the ring-screw and remove the spin cable from the handle post.
2. Remove the air resister (or add one).
3. Reattach the spin cable through the two holes of the handle post (go through the top hole first). The length of cable should be five inches between the handle post and the first air resister. And this length should be the same on both trainers.
4. Attach and tighten the ring-screw up against the post using a screw driver. Finally, attach the plastic end tab.
