Kromski Prelude Tension Peg | Replacement Brake Adjustment Knob

The Anatomy of a “Stepless” Spin

In 2026, precision is the mark of a master spinner. The Kromski Prelude utilizes a traditional Scotch Tension system where the brake band rests in the bobbin groove. This wooden peg is the mechanical “brain” of that system. Unlike plastic ratchets that force you into pre-set “clicks,” this peg offers infinite granularity. You can rotate it by a fraction of a millimeter to perfectly balance your yarn’s twist, preventing the “jerking” motion that can snap fine fibers or cause uneven plying.

Friction-Fit Reliability

The genius of the Kromski design lies in the tapered shaft. The peg is engineered to seat snugly into the Prelude’s upright, using natural wood-on-wood friction to lock its position. This prevents “tension creep”—the annoying habit some wheels have of loosening their tension during a vigorous treadling session. It’s a low-tech, high-performance solution that has stood the test of time.

Aesthetic Harmony

Kromski understands that the Prelude is often a centerpiece of a room. This peg is turned with a comfortable, ergonomic flare and is finished in Clear Lacquer, Walnut, or Polished Unfinished wood to match your wheel’s grain perfectly. It’s not just a spare part; it’s a restoration of your wheel’s original beauty and function.
