Bob Jackson (Vigorelli, etc)

When I was enquiring I was told the 23" and 23.5" frames both had a 22.75" top tube. I don't think they're square in all sizes, and I don't think the angles are all 73°, especially in the smaller sizes.

For some reason Bob Jackson don't like publishing a geo chart but if you email them they will respond to specific queries regarding sizing.

I thought they'd be around 73... was hoping it would be more 74 or 75...

The size i'm interested in is 55cm (22 inches)
