Steps

  1. 1

    Master nosegrinds first

    A crooked grind is a nosegrind with an angle. If nosegrinds aren't consistent, work on those first.

    Force
    ●●○○○
    Direction
    forward
    Weight
    front
    TipThe lock-in is the same as a nosegrind — the angle comes from the approach.
  2. 2

    Approach at sharper angle

    Approach the ledge at a sharper frontside angle than a nosegrind.

    Force
    ●●○○○
    Direction
    forward
    Weight
    centered
    TipThe approach angle determines the K-grind angle. Experiment.
  3. 3

    Lock nose truck while angled

    Land the nose truck but keep your body's angle maintained. Don't square up to the ledge.

    Force
    ●●●●○
    Direction
    up
    Weight
    front
    TipYou're fighting the instinct to align parallel. Stay angled.
  4. 4

    Grind through the angle

    Maintain the 45° angle throughout the grind.

    Force
    ●●●○○
    Direction
    forward
    Weight
    front
    TipK-grinds are shorter than nosegrinds because the angle creates more resistance.
  5. 5

    Pivot or pop out

    Exit by pivoting to regular position and rolling away, or popping a small ollie.

    Force
    ●●●○○
    Direction
    up
    Weight
    centered
    TipA clean K-grind exit maintains the angle all the way through the pop-out.

Common mistakes

Tail catching ledge

What
The tail catches the ledge because of the angle.
Why
Back truck too close to ledge surface.
Fix
Ensure your ollie-in clears the back truck fully.

Angle straightening mid-grind

What
You lock in crooked but the board squares up during the grind.
Why
Instinct to align parallel is overriding your commitment.
Fix
Use your back foot pressure to actively maintain the tail's position throughout.

Why this works

The mechanics behind the trick

Board
The nose truck is locked onto the obstacle but the board angles toward your toe side. This creates a unique visual with the tail hanging at a distinctive angle.
Feet
The angle is maintained by keeping pressure on the nose truck while your back foot holds the tail at the desired angle.
Weight
Weight on the nose truck, with a slight frontside lean to maintain the angle.

Is the Crooked Grind hard to learn?
