Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

chain slip? cog slip?

while i was riding home from work tonight my my cranks kept slipping, it felt like when you hit a patch of ice , or my chain sliped off. It seemed to be comming from my rear cog. It only happened when i was standing up, almost endo'ed twice. What gives?

probably your lockring isn't tight enough. go out, stand up and crank on the pedals, or jam the front wheel against a wall and crank the pedals, then tighten the lockring down.

Maybe a seized link in the chain? Weird that it only happens when standing though.

I've had this problem before. In really cold weather, or sometimes in ice/snow conditions, or just randomly, the pawls in the freewheel fail to engage because they freeze up, or the grease is too thick as a result of cold, or bad voodoo.
This just makes the freewheel cog just become free with no engagement. It's weird, but it always kicks in again.
I had that happen a few times today. It freaked me out at the time.

It's a cold one out there. It's almost certainly the grease being too viscous. Have I mentioned how glad that I got my fixed/free mtb wheel flip-flop built up just in time for this nonsense?

You can tell if its chain slip because: 1. It sounds like Satan has unleased his full fury on your cog, and, 2. it feels like it, and it almost always ends up with a meeting of privates and top-tube.

Whereas if it just goes "wahey!" and slips, without that Godsawful noise, it'll be your pawls. You might want to get the block off and get some WD-40 in there to loosen things up. Stripping and cleaning a freewheel is a righteous arse.

Check the threads on the hub,cog and lock ring. be careful in traffic it becomes a major problem.

I second the Bostonians - it's probably the cold. Take the bike into your house for an hour, give it some hot chocolate and let it warm up its toes, then ride it around the living room.
