so tonight i some how threw my chain...
I think it's because I have quick release on my rear tire and it got loose. anyway...
i threw my chain and somehow bent my skewer, i think? because now I can't even loosen my quick release by hand. I mena, with a cresent wrench, i could,. I sat downtown trying to do it and in frustration threw my bike down and magically was able to tighten it enough to be able to ride... though i couldn't brake or peddle hard.
My bike is currently locked up downtown because i couldn't ride it home.
bluhh. i am sad.

i have no advice, just lots of, "dude, that sucks," and, "i remember walking my fucked up bike home up cap. hill with a broken collarbone. glad you're not dead."

If I could find it, I would put in a link to Warren Zevon's "My Shit's Fucked Up"

I think i fixed it.
I got it today at took the quick release off and replaced it w/ the bolt from my front wheel. I'm not sure how well it will work though, since the bolt is a bit too short? so I couldn't put any washers on there w/ the nuts... Is that bad?

na, it'll hold, just don't ride over glass, then you don't get flats and never ahve to touch them again. this wil get you by till you swicth to the solid axle.

Yes, get rid of that QR rear axle, those things are trouble on a fixed gear bike.

ah, it's nice.. not having to reset my wheel everytime I go to ride.

Fool of a Took. That's not luck, that's poor technique.
Quick primer on wheel physics.
Spokes fail when a force or combination of forces causes the spoke to deform (bend or twist) enough to exceed the ability of the spokes to resist such deformation.
A properly tensioned spoke is incredibly strong along the long axis. That means it can deal with high dynamic loads fairly well.
When you tighten a spoke, you want all the torque you apply at the spoke nipple to be stored in the spoke as tension. Because of friction between the spoke nipple and the spoke threads, and the between the spoke nipple and the rim, and some torque gets stored as torsional forces.
This is bad. Most solids, they generally don't deal with torsion (being twisted) very well.
When you true your wheels, take a minute and drip a little oil in and around your spoke nipples. Lubricating them reduces the amount of torque (twisting force) stored in your spokes.
Also, when you think you are done truing them, load the wheel a little. I put the wheel on the ground and lean on it a bit (lean along the axis of the spokes). That little bit of load helps the spokes release torque in a more controlled manner. The pinging you hear is a good thing. Then check the wheel again. You might have to make a few minor corrections but that's about it.

I rode with a QR axle back in the 80s but I did not do a lot of skidding. Now that I skid so much, a QR won't hold up. They bend. If you use a Shimano QR skewer and good lock-nuts on your hubs, you can use a QR Just don't skid.

oh, the spoke was bent pretty bad. I had a run in w/ a tree limb, and everytime I went to a shop to get a new spoke they told me i had to special order because they're black?
So I just had my tighten the spoke up. He told me it was most likely going to snap because it was bent so badly, so....
I expected ti to happen.
But since I've been riding since last april, shit has broke on my bike like every other week.

i also noticed that back wheel is not lined up at all. I can compare it to the hole drilled for the brake... it's off quite a bit. haha.

Its good you didnt mix the black and silver spokes. i did that once and the place where the two spokes touch cought on fire because the coastings arent compatible.
