So I can shoulder the bike and not have a bottle cage digging me in the kidney.
It also has road fork blades for chainstays so I can run a narrow BB axle. Clearance for 1.95 max.
Field bikes, the known brand, are from Sheffield but this was made by someone else. Denis Field who set up near Falmouth. He built road frames and agreed to do this one-off. When he finish he said he had had to throw the book away and would never do another. He also said I could have had it in 753 if I’d asked!
