Sooo, I JUST finished my first bike build (a 1987 world sport fixed conversion) and went outside to give it a little test ride in the parking lot. It was also my first time ever riding a fixed gear. I had a buncha fun messing around for 15 minutes and then remembered a few tips from guys saying "As soon as you get your **** put together, ride up a big hill then go re-tightin your lock ring". I had noticed that when I pushed forward on the pedal hard the crank felt like it slipped about a quarter of a turn, and then it would do it again in the reverse direction when I would try to skid abruptly. I assumed it was because the lock ring wasn't tight enough and the cog was screwing and unscrewing back and forth just a little bit.
Soo, I think to myself "well I'll head down this hill to my house entrance and tighten this sucker up, and then get started assembling my front brake". So I pick up a little more speed than intended and decide to try my luck at my first big-boy skid and... what do you know, my pedal just slipped on through and around and around my feet went. I realized immediately what happened and swerved a couple times (almost hitting a cadillac on the second swoop) and decided I had to pick something to run into before I went further down the steeper part of the hill. I picked a curb right in front of a fire hydrant (was my only option really). I hit the curb dead on and flew over the handle bars and landed right on the hydrant, haha. Scraped my arm up and popped my front tire. Also totally kinked my handlebars but it appears the stem just turned rather than anything getting bent.
Definitely an overall well-learned lesson. My question is... how do I know how tight I need to put my lock ring? When I put it back on I'm gonna put ALL of my effort into it... hopefully that will be enough, haha.
Has this, or something similar, ever happened to you? =O
