Cycling Lingo 104

CHAIN SUCK
[cheyn*suk]


A mechanical bicycle failure that results in a lock up of the drive train. It occurs when, while downshifting under load from the middle to the smallest chain ring, the chain does not immediately disengage from the middle ring and gets carried upward until it wedges between the chainwheels and the chainstay. This jams the crankset. Since you probably wouldn't have been shifting to the granny if you weren't already busting your ass up a hill, the sudden lock up of the drive train deprives you of what little momentum, and enjoyment, you had.

I recently discovered a variation of this phenomenon, which I have labeled Reverse Chain Suck.
I can not explain the cause of reverse chain suck; however, I can tell you that it certainly sucks.

Ah yes, Reverse Chainsuck. Created by the terrible 'crank vacuum vortex', and made worse by extremist front derailluer over range (bike terrorism).
