my chain always comes off!
I'm racing this year, and I have a major problem: my chain comes off whenever I go fast! It has come off 6 times in 3 weeks. It only has a half inch of slack, which is ideal for racing. How do I keep it from coming off? It's making me develop a fear of going fast.

Make sure that your sprocket isn't bent and that you chainring bolt and pinch bolts(on your crank, if you have a 3 piece) are all tight. If they're loose your sprocket could wobble side to side making it out of line with your chain.

i dont really like kickflips if you're not doing anything else, but if you do it out of a grind or during a spin, it could be cool. these little ****** kids near my house do crankflips down stairs.

Wow, I've not heard of this problem, at least not as severe. In more years of racing
than I care to admit, I can count on one hand the numbet of times I've dropped a chain - always when shifting from the small to the large chain ring to sprint over the top of a hill. That was with the old Sedis chains and friction shifters.
It's gotta be a bent chain ring or frame or something that is causing misalignment
of the drive train. When's that last time you replaced the chain or for that matter
the cog set? Does the bike shift smoothly otherwise?
sun
ps: With decent derailluers chain slack shouldn't be an issue here unless it's
really slack. Used to cut them down from 120 to 108 links for racing. Worked for all
but big - big combination.

Gee,
Should've checked the forum. I'm old and rode (at race pace)about 70 miles in the mountains today. So I'm tired too.

Chaim should be fairly tight, 1/2" is more than I'd want racing. Is your chainring centered, meaning does it get looser/tighter depending on which point in the rotation the crank is?

turn the bike over and make sure the chain is going in a straight line between the freewheel and chainwheel (no curving between em). this was haunting me all last season in fact. the countless hours i put into messing with that chain. oy. anyway straighten out the chain by adding spacers to the cranks (moving them out more, hopefully alighned the gears). make sure ur backwheel is tensioned straight (not pointing to one side). u may also try gettin a good chain like the ACS one, which won't flex as much. oh and btw, for racing you should be able to run close to an inch of chain play. hope that helps dain, as i said i had to put up with that chain crap too.
