FRAME POSITION ADJUSTMENT

Shifting the frame backward on the boot changes the turning pivot point. Small adjustment, big impact on agility and endurance.

What happens when you move the frame back​

The turning pivot (转向点) shifts rearward, closer to the ankle joint. Since the ankle is where most turning originates, closer pivot = faster turning response.

Three observed effects​

More agile turning​

  • Full-foot-contact sliding turns become significantly more responsive
  • Frame length doesn't change → total sliding distance stays the same
  • Crazy moves become noticeably easier — faster entry speed, higher explosiveness

Longer sessions​

  • Less effort per turn → energy savings compound over time
  • Same physical state that used to last ~2 hours now lasts 3-4 hours
  • Particularly noticeable during high-speed and explosive skating

Single-wheel trade-off​

  • Support shifts from full-point to floating-point (浮点)
  • Floating-point = less effort to hold, but harder to turn while on one wheel
  • Expect to "drop foot" more often initially until you adapt

Why more agile?​

  • When you rotate your ankle or hip, the response speed depends on distance from the rotation axis to the contact patch
  • Frame backward = turning contact patch closer to ankle = faster angular response
  • Same principle as why shorter lever arms turn faster

Caveat: sliding saturation​

  • Backward frame + existing habits → tendency to ride toe wheels more
  • This shortens overall sliding arc per move
  • Fix: consciously practice full-foot-contact (全脚贴地) movements
  • Full-foot contact + backward frame = comfortable turning without toe-riding
