Endless RB 100 Frames ride with a balanced rocker at 4x100 and flat at 3x110. Perfect for use on Rollerblade Twister Adapt Hyperskates, and other 165mm compatible skates. They include longitudinal mounting slots for dialing in front-back frame alignment.

The 3x125 can be pulled off on some models (FR Skates FR1, FR2, FR3, FRX, Rollerblade RB80, RB110, RBPro, RB Cruiser, Twister Edge). Longitudinal mounting slots allow for optimized front-back alignment with Rollerblade and Adapt skates.

For centered mounting on FR/Seba boots and Micro MT Plus: push the frame forward (bolt sits towards the rear of slot). For centered mounting on Rollerblade or Adapt boots: push frame backward (bolt sits towards the front of slot)
