(1) The fork rake was determined using a test fork which had
adjustable rake. The bikes were riden for a few weeks adjusting the rake
for handling and personal taste. The rake was then measured and
permanent forks built.
(2) Most shifting is done with the Sachs 3x7. However, a triple crank
is installed to obtain high gears and extreme low gears for touring.
Chain rings are shifted by hand when stopped or, with dexterity, while
riding. With this arrangement good spacing is obtained from a low gear
of around 15 gear inches to a high of 125 gear inches.
