Ephgrave No. 1 track - 1959
Owned by: Mario Romeo
Three views of long spearpoint No. 1 head lugs plus Cinelli 'badged' steel stem and Pista bars
Inch-pitch drive with block chain, 27T chainring, 7T sprocket giving a gear of 104" measured the UK way.
With a double link removed the wheelbase would be shortened to good effect, but taking links out of block chains is not easy.
