"The special part of Nickıs bikes lies in his joining the tubes...
He of course starts with an extremely accurate tube cut and finish
that lets him basically call out angles down to fractions of degrees.
This allows for geometry with true nuance as I was able to spec
very slight changes to the Geometry that I have used on the past
two or three other custom frames in just the past year
(rough life, but some one has to...). I specified angles down
to the hundredth of degree and Nick knocked em out using some
fairly expensive gear..."
Ooohh! Nuances.
Fifteen yards for illegal use of ellipses...
