Owned By: David Rapley

Frame1933 Ganna Cambio Vittoria; frame size 22" seat tube, 22" top tube. With chain oiler in the seat tube. Chain stays are unusual plaintapered tubes.
WheelsGanna hubs, wood rims 36 spoke and tubular tyres (we, in Australia, call them singles).
ChainsetGanna 6¾" cranks unusual in that the chain wheel screws into the crank with a large central thread.
PedalsSheffield Sprint, REG Special Clips with Binda straps
GearsCambio Vittoria three speed with 1/8 chain. The system is really only a chain tensioner the change effected by slacking the chain, pedalingbackwards and directing the chain with the fingers !
BrakesUniversal pre-WWII steel callipers
Stem/BarsNanni Torino stem and bars. Head set Ganna
SaddleItalia
Extra Details I think the bike is correct apart from the brakes which may be as late as 1939. There is no evidence of the later Vittoria mechanical 'chain mover'having been fitted.
Lower seat tube tube with in-tube oiler on down position to allow oil to drip onto chain, the oiler is tilted to the vertical to cut off supply Cambio Vittoria gear, Ganna chainset and Sheffield Sprint pedals
