My bike is a Schwinn Suburban, 21-speed -- 3-speed front, 7-speed rear; bike
is ten days old. Yes, I know, it's an under-$200-department-store bike but
it's my bike.
Something that appears to be associated with the front crank or the right
pedal is going "tick" as I pedal. Here are the details:
-- When I reach the point in a pedal stroke where the right pedal is at the
top of the crank (and the left pedal at the bottom of the crank), something
goes "tick".
-- The tick is definitely coming from the front and seems to be associated
with the right pedal, or, the right pedal is transmitting the tick.
-- At times the tick is so strong I feel a slight bump in the sole of my
right foot; at other times, it's barely audible.
-- Makes no difference the gear I am in (I ran through all 21 this morning),
speed, pumping hard, not pumping -- it's there all the time.
-- It does NOT tick if I am coasting.
I know little to nothing about the derailleur system but I examined the
front crank and gears, and examined the chain, looking for obvious defects.
Nothing found. I held the bike upright and pushed and pulled very hard on
the pedals and the crank assembly, trying to move things up and down, in and
out, side to side -- no movement.
Any ideas?
I am a competent mechanic, having built and rebuilt old VW Bug engines,
brakes, and suspensions for years -- so -- I have two big tool boxes and am
not afraid to dive into the bike.
Thanks.
