I'm starting to think I don't know how to ride...

I just got my new cyclyng shoes and had my clipless pedals installed today and on my way back home I got stopped at a red light. When it turned green I began to pedal, and my chain slipped off, I look down AND MY DAMN THIRD(outer) CRANK IS BENT . This wouldn't be so bad, but the bottom bracket on my road bike just went out.

I have a Haro V2 hardtail that I've been using to commute and it hasn't even been a week since I got it, then this happens.

To boot I'm not even that big of a Clyde. I'm 6'2" 250 and to give an example of my build I fight MMA and compete in strongman-style competitions. Do you guys have these problems or am I just an ignoramus on a bike?

Out fishing with Annie on his lap, a cigar in one hand and a ginger ale in the other, watching the sunset.

Seems to me you meet the definition of Clyde in more than size, but sheer power as well. I guess you need to spec for power and not weight savings. Gonna be the nature of the beast, I'm afraid.....ya big lummox!

Just a picky technical thing, it's your outer chainring that's bent. Two crankarms and one bottom bracket comprise the main body of "the crank" which has a spider on one side to attach your chainrings.

I'm a big guy who used to powerlift, and I've bent my share of cheap chainrings. Buy the strongest chainrings that your LBS can get for you, and you'll have less problems. I think that the issue with us big & strong riders has to do with a combination of stress fatigue on the chainrings from cross-gearing and high force.
From a dead standstill, many of us gear down to the largest cog to get an easier start. Do that from the large ring, and you've got some good side torque on that ring. The large ring has the longest fulcrum (from the bolts) so the stress to the metal is greater.
Cap that with the massive force that a 100Kg+ rider generates, and you've got a recipe for bending chainrings like they were made of taffy.

Try dead starts from your middle ring and a middle cog to keep your chainline straighter, and spin up through your gears rather than standing and mashing a high gear off the starting line.

Great advice Clifton.

You're now in the market for a new crankset, and let me recommend the Sugino 46-36-26 touring crankset. I am 210 and I like to start off in the middle chainring to avoid stress on the other. In fact around the city I don't have to switch out of the 36 tooth chainring that much unless trying to go 18mph+ on flats or climb hills.

I'm a cranker myself - but riding in the city from many dead starts I've found that the middle is easier to get going, won't stress my knees, and most importantly harder to bend then the outer one (which I almost did on a brand new chainring). I second the Sugino though I put on a 48 top chainring on it (wanted 50 or 52 but they wouldn't let me).
