I had a spill today and have a couple of questions.

My crank arms had some play in them (a thunk with each rotation). Having no tools, I decided to return home. Arriving first at an intersection when the light turned green, I mashed down on the pedals. After about two strokes, one of the arms came loose. I lost balance and went down right in the intersection. Is this a common occurence? (Not going down, but having loose crank arms.......... Thankfully the SUV behind me only came within a foot from running over me.)

My helmet has quite visable damage. Should I junk it, and get a new one?

I don't know how common the loose crank arms are (never had that problem), but DEFINATELY JUNK THE HELMET!! A helmet is designed to break apart to absorb the energy of an impact. Visible damage is a definate indication that your helmet has done it's job. Hang it on the wall as Pop-Art, but don't wear it again. Get a new one. (aren't you glad you had it on?)

sounds like a bad owwee - I hope you weren't travelling too fast when you biffed it?

Loose cranks are not common, nor are they good. Sounds like a poor install.

Be on the safe side and replace the helmet - it's done its "job" as a shock absorber, so to speak. Any compromise to the integrity of the shell will negate the helmets' effectiveness in your next accident, however minor. Even if you were barely moving forward, the force of your head meeting the pavement could crack the interior. It only takes about 8lbs of pressure to damage EPS foam.

Most manufacturers have a replacement policy, you only have to cover shipping (they send the same model or model year equivalent). Call them directly for more info on where to send the helmet.

I had virtually the same accident about a year ago on my pista, and what my fix was (I truly biffed the crank arms)was to switch out my bottom bracket for a Shimano splined bottome bracket and to use a bit of loctite on the threads holding the new cranks (not the cranks themselves). I don't know if it was one thing I fixed that made the difference or a little bit of everything, but it's hunkydory now.

As for the helmet, didn't you want a new one anyway?:)

2 biffs in one day (one ride even!) is definitely NOT a common occurrence... CONGRATS!

It's now been 19 days since I crashed, and I hope to be riding again by this coming weekend. After seeing the bruises and muscle damage to my left thigh and buttock, I can't begin to imagine what my head would be like if I weren't wearing a helmet. My 10 month-old Trek Vapor helmet's styrofoam liner split, and my LBS replaced it for free. They didn't even make me send it back to Trek.
I've now become one of those pains-in-the-you-know-where that preaches to everyone about wearing helmets. By the way, I gave the new Trek away to someone who was previously not wearing one, and I now have a Louis Garneau Globe, which also has the one-year free replacement deal. Hope I don't need this guarantee...and that you won't need to replace the new one you'll be getting!
