Slipping/Jerking Crank

I did post this on the SS/FG thread since I dont technically bike on a track, so sorry to all the people who post on both forums.

Since I ride on the streets, I skid a lot.
Well, sometimes when Im skidding for a while, ill pedal forward and my crank will suddenly jerk forward as if the chain is broken (when its not). Its like the cog/lockring are sliping, when my lockring is tight already.


My friend whose been riding fixed for a while says that after skidding, its just the cog tightening itself back onto the hub.

Anyone had experience with this? Cranks suddenly jerking forward? (I know its not a problem with the cranks since its fixed-gear and the only way it jerks forward like that if its something with the cog/lockring.)

There's a very easy solution to this problem: a brake.

This is a mechanical issue. Post such questions in the Mechanics forum.

To answer your question, you cog is loose. You need special tools to tighten it and the lockring. Be careful and take it to a local shop. They should tighten it for free or maybe a small tip.
