Ganna (Cambio Vittoria) - 1933
Owned by: David Rapley
| Frame |
1933 Ganna Cambio Vittoria; frame size 22" seat tube, 22" top tube. With chain oiler in the seat tube. Chain stays are unusual plaintapered tubes. |
| Wheels |
Ganna hubs, wood rims 36 spoke and
tubular tyres (we, in Australia, call them singles). |
| Chainset | Ganna 6¾" cranks unusual in that the
chain wheel screws into the crank with a large central thread. |
| Pedals | Sheffield Sprint, REG Special Clips with Binda
straps |
| Gears | Cambio 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 ! |
| Brakes | Universal pre-WWII steel callipers |
| Stem/Bars | Nanni Torino stem and bars. Head set Ganna |
| Saddle | Italia |
| 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. |

the oiler is tilted to the vertical to cut off supply
