aBoUt shimmy

Some cyclists have experienced disturbing
"shimmy" or "vibration" at certain speeds.
symptom is rarely reported and there is no
agreement among experts as to the cause.
Among the proposed causes of shimmy are: a
loose headset, frame alignment problems, weight
of front wheel magnets for cycle computers, and
spoke tension.
Larger riders on larger frames are thought by some
to be more likely to experience such vibration.
If you experience such a vibration, gently apply
the brakes and slow down. Another suggestion is
to press your leg against the top tube as you slow
down.

What is it?
"Toe clip overlap" or "toe overlap" describes the
toe of your shoe or toe clip contacting the front tire
(or front fender). This may occur when the pedal
with your shoe (with or without a toe clip) is all the
way forward and the front wheel is turned sharply
to a position where the toe or toe clip can contact
the tire (or fender). If you ride with clipless pedals,
attach your riding shoes to the pedals and check
for front tire clearance.

"Toe clip overlap" is common on small frame size
bicycles. It is simple to avoid any contact with
the front tire: have the inside pedal up before
beginning a turn. As you turn to the left, the inside
(left) pedal should be positioned at twelve o'clock.
As you turn to the right, the inside (right) pedal
should be positioned at twelve o'clock. Having
the inside pedal up will prevent any toe clip-to-tire
contact and maximize cornering ground clearance.
Learn to make it your habit on any sized bike.
Whether or not you have overlap, or how much
overlap you have can be changed. Be aware that
toe clearance can be increased or decreased by
changes in crank arm length, size of pedals or toe
clips used, size of tires used, addition of fenders,
size/design of shoes worn.
