Newly-redesigned back uprights permit mounting of graphite aerodynamic disks. The compact back uprights are tiny in proportions but because of the certain composite mixture used, they are very good. As a result of perfect molding, bearings match the steering block without additional play for maximum safety and handling.
The straight back uprights function two easily-adjustable top roll center roles which are useful for traction modification. The uprights also work two human body mount modification jobs with regards to the number of human body used. Also included are paid down and longer pivot ball bones for optimum set-up modification.
