    Ever throw a chain?

    Been lurking on the ss board for a few months now. I had a 70's Raleigh 10 speed converted to fixed about 4 months ago and have been loving it. Until this past Sunday, that is, when one of the screws attaching the chain ring to the pedal arm popped, and the chain jumped off. This while making a maneuver to get around a left turning car. Luckily, the driver and I made eye contact and I was going slow enough to avoid a catastrophic accident. Brakes are good when you need them. I feel lucky nothing happened, but I have greater respect for the forces involved in the drivetrain.

    damn son

    make sure your chainring bolts are always tight!

    and that your chain isn't too slack. i haven't thrown a chain in a long time *knocks on wood*

    if you have a decent chain tension and proper technique you shouldn't ever have any problems with throwing chains

    Twice. Both times I used the foot in the rear triangle technique. I've been keeping my drive train in really nice condition these days

    Barring some sort of catastrophic failure, you should never throw your chain. Its not that hard to stick your finger or tip of your foot down there everyday to make sure your chain is adequately tensioned...if its too loose, slide your wheel back. Once a month or so, check the tightness of your lockring, cranks, chainring bolts, etc. It takes less than 5 minutes to do that.

    I have this friend who I converted his old Raleigh...I keep reminding him to check his chain tension, chainring bolts etc., but he just doesn't seem to understand the seriousness of the whole thing, no matter how many times I've explained to him the dangers of throwing a chain on a fixie. It seriously worries me.

    to tell another members story.....

    at Monstertrack 7's pre-ride-which went over the traffic lane of the w-burg bridge, on the descent, making butter at 40k, my buddy dropped his chain. it jammed between the seatstay and the cog. he went for the craziest surprise skid towards the median. he was fine. shaken, but OK.

    I skip a crapload every day, so I check my tension every three days or so. Still get suprises sometimes... argh.
    I ride with pants so tight that they're spandex.

    New build, On-one, ghetto hub...late night, first ride, standing sprint.

    Chain throw, faceplant, high speed, sound of helmet scraping ground. Bloodloss.

    Riding towards the avenue I take home, at a pace faster than normal, light turns red and I go for a skip my chain jumps right off, totally taken by storm and with surprisingly dry pants I pull on to the sidewalk and into the grass of the park to slow myself down and perform that scary emergency dismount. Now I am extremely paranoid about my chain tension and every one elses' I see. It's always worth taking a couple minutes of your time to make sure your gear is all good to go.

    mashing up a hill, and then all of a sudden finding it much easier to pedal.

    "ho ho ho" i laughed, thankful that brakes exist and that i stopped/noticed before the scenery started moving the wrong way.

    stoopid crooked chainline.

    awhile ago i was having trouble with my real wheel shifting forward (QR) so it happened repeatedly. freaky, but i'm on a SS so i managed to stop alright.

    however, i was riding with someone who had a spectacular crash the first time trying a conversion... as i watched from behind in horror. would have been ok if not for the curb that got in the way

    did it once on my schwinn bmx riding to my friend's house when i was about 10. the sprocket went in to my calf, putting grease in the cut. nothing hurt worse in my life, not even when i broke my collar bone flipping over my handlebars when i was 19. when i shave my legs for racing season, you can still (barely) see the marks of the teeth of the sproket running up my leg.

    I had a really bad incident 2 years ago while riding a geared mountain bike in heavy traffic in Paris. I was out of the saddle going at a good clip, with a big parcel truck right behind me when my chain slips off.

    It wouldn't have been too bad except for the fact that I was out of the saddle and my testes come down hard on the top tube. Fortunately, I'm running platforms and put my feet down and Fred Flinstone it, trying just to stay up and get out of the way of this huge @ss truck behind me. Alas, I lived. My brother who was riding with me felt the need to say "You almost just died, you know that right?". Check your drivetrain often, gentlemen.

    Don't lie, you're totally proud of it, aren't you?

    this is why i run tugnuts. also because the surly tugnuts look kinda like little flames coming out of my track ends so i can pretend that i have rocket boosters.

    totally. i'm proud of all of my cycling-related scars; i even try to have people touch where the break happened in my collarbone. it's a badge of pride in a way.

    Happened last week. Biopace rings flex a bit because I was out of the saddle after a corner and the chain jumped off. Somehow the teeth gouged my left leg, so two sets of scars.

    i threw my chain one time while going through an underpass in cambridge, it was really scary because all of a sudden i was coasting, fortunately i was running a brake and i was heading towards the uphill. Fortunately, I learned my lesson about minding my chain tension rather painlessly. One of the worst sensations in the world though.

    I've thrown a chain no less than 4 times. It's never resulted in a crash for me, even though 2 of them were on steep downhills. If you going to run a hacked together conversion, run brakes folks.
