Chain
suck
|
Chain
suck occurs primarily when downshifting under load from the middle
to the smallest chainring.
The bottom run of the chain may not immediately disengage from the
middle ring, and can get carried upward until it wedges betwixt the
chainwheels and the right chainstay.
This jams the crankset.
Since you probably wouldn't have been shifting to the granny
if you weren't already climbing, the sudden lock-up of the drive
train deprives you of what little momentum you had, and you are very
likely to stall and fall. Chain suck is commonly caused by bent
chainring teeth, dirty chains, or, occasionally, burrs on the teeth
of new chainwheels. Jonathan Levy has an extensive Web
site about Chain Suck. (actual link to http://fagan.co.za/Bikes/Csuck/)

Tensioner

An
idler pulley used to adjust the tension of a tandem synch
chain. This
system is used on inexpensive tandems, as a cheap substitute for an eccentric
bottom bracket. A
device used on some one-speed bicycles to adjust the chain tension
by pulling back on the rear
axle with a screw
thread. One popular type used on BMX bicycles is called a "banjo
bolt."
