Speed Star F.3

The F.3 is extremely similar in design to the more common Mk.3, and very often mistaken for its brother.  The F.3. shared sizing options with the F.2. and Star Mesh, with the standard F series colour options of silver, red, orange, gold and black.  The F.3. is sometimes referred to specifically the Speed Star RX-7, with an SA22 specific size of 13 6J +19 offered, and featured in some advertisements at the time.

Sizing aside, the way to distinguish the F.3 from the Mk.3 is the alignment of wheel assembly bolts with the narrower spokes.  On the Mk.3 the battery primary spokes will always align with assembly bolts.
