Compact backside uprights are tiny in proportions but are extremely strong because of the special composite mixture utilized. Thanks to superior molding tolerances, bearings fit completely to the back uprights without any extra play, offering optimum security.
Features two mounting jobs for the top roll center linkage to allow simple roll center modifications.
The new back uprights take care of the optional graphite Aero Discs #335370 for improved security and traction.
