hi, I'm Peter, you may remember me from some thread a couple weeks ago when my hub a splode.
So I built a wheel with a 6 bolt disc cog. It's pretty strong stuff. So strong that when I dropped the chain coming down a hill, the cog wrapped the loose chain and did this.
(possibly my bad -- changed chainrings, should have checked the tension after it had settled in for a few miles, I guess--or maybe my chainstays are just too flexible)
I am now taking bets on what the next major fixed gear mechanical failure will be.

Lucky break actually, if you'll excuse the pun. Nicer than having your rear wheel jam and go into a permanent skid, or tear a bunch of spokes out on the drive side.

yeah, i had the same thought after assessing the damage. Wish I could figure out what made it drop though. Chainline measures out perfectly, no signs of axle slipping.

$20 says that the next failure will be of a soft tissue or skeletal kind.

I did the same thing, only it wasn't on a fixie, and it was a stick, and my fender stays, and i skidded nicely to a stop, got off the bike, and took the stick out. The great thing about soft aluminum fender stays is that you can bend them back to a point where you can ride the bike home. I suppose I should have the spoke tension on the wheel checked, but it's still true, so why bother?

It looks like your cog wasn't threaded on stright. Did a bike shop put that on?
When thechain jumps off your drivetrain the chain will either lock up the rear wheel or you'll start coasting. Most offten the chain will fall off of the chainring because your spinning too fast and you just went over a bunch of bumps. Or the chainring might be bent and missing a few teath. You don't want your chain tight because the friction will slow you down and wair out your compnets faster. But you don't want it too loose because it might fall off. If you hold your bike horizontal and shake it as you spin the rear wheel, the chain shouldn't fall off.
Don't loose a finger. Spin the wheel-not the cranks when applying lube. Getting a finger stuck between the chain and the chainring on a noncoasting bicycle hurts!
You have a break right? Fixed gears are good for the track or flat citys with salty winters! Spin the fuck out of the bike. Prefect for urban riding you can accelirate thrue the light but you max out quick. Its good for training too! None of this hurkey jurky chuffer riding style. Go with the Flow. Its not cool to allmost get hit. It sucks to get a ticket for riding your bike. You can allways run from the cars, its just the motorcycles that you can't get away from.
Stay visiable, cars will claim that they didn't see you. Dress like joby! A bag like ryans "see me." White helmet. Rear light. Front flashing headlight. You wouldn't drive a car with out headlights. Defensive riding. Don't stop your bicycle behind a vehicle at a light. Look at the front tires to see where the car really is going.
Wow, what a rant! Still can't spell, just trying to share some things that I've learned from 4 years of doing this. Not hating, rubber side down. Hope all is well.
