The Standard Fast whorl is the second of the two whorls included with the Kromski Sonata Encore, and the natural next step up from the whorl that ships standard with the Fantasia. If you spin fingering, sock yarn, or fine three-ply singles, this is the whorl that lives on your flyer.

Two ratio grooves on one whorl. The slower groove handles balanced fingering-weight three-ply. The faster groove holds enough twist for tight sock singles and finer worsted-spun yarns. Swap to the Extra Fast whorl when you move to laceweight or fine cotton.

Fits the Kromski Fantasia and Sonata Encore

This is a magnetic-flyer whorl. It will fit any Kromski wheel with a magnetic flyer head:

  • Kromski Fantasia (all production)
  • Kromski Sonata Encore (one of the two whorls included standard)
  • Original Sonata wheels upgraded with the Magnetic Sonata Flyer Head Set

If you have an original (pre-Encore) Sonata with the traditional non-magnetic mother of all, this whorl will not fit until you add the magnetic flyer upgrade.

Ratios on this whorl

Drive wheel diameter changes the effective ratio, so the same whorl produces slightly different ratios on each wheel.

Wheel Low ratio High ratio
Fantasia (18 In drive wheel) 10:1 14:1
Sonata Encore (19 In drive wheel) 10.5:1 15:1

The four magnetic flyer whorls

Kromski makes four interchangeable magnetic flyer whorls. Each one covers a different part of the spinning range:

Whorl Fantasia ratios Sonata Encore ratios Best for
Extra Slow (Jumbo) 4:1 and 6:1 4.5:1 and 6.5:1 Bulky, art yarn, jumbo flyer plying
Standard Slow 5:1 and 8:1 5.5:1 and 9.5:1 DK to worsted, general purpose
