This instruction book covers a range of eight straight-handlebar no-nonsense bicycles, two of which have derailleur gears. These two are the 111-533 ‘Virage’ for men and the 112-523 ‘Diana’ for women. Both appear to use a three speed freewheel with 16, 19 and 22 tooth cogs. The terrain must be pleasantly flat around Penza.

The Perm derailleur is shown on page 21.
