Sheared off pedal - How's that happen?
On Apr 28, 1:43*pm, HazeRider wrote:
I discovered the hard way yesterday that I should be concerned about possibility that the pedals on my bike might shear right off in the middle of a ride. While crossing a major intersection and standing on the pedals to accelerate after being at a complete stop the right pedal of my Look Keo Sprints sheared straight off just as I passed the traffic throwning me face first into the asphalt. It happened so fast I never perceived the going down portion of this. One second I'm up and a nano second latter my head and face do a seven-beat stacatto drum riff on the asphalt. Major thanks to the lady that stopped in her car and helped me. Also the police and rescue squad folks. A cop was on scene in mere seconds and the ambulance in less that two minutes. Amazing nothing broken on me. I need a Phantom of the Opera mask for a few weeks and Advil is my best friend. The bike was not as luckly as me. Major damage to handelbars, computer, sunglass, helmet, etc. To the question. How the hell can a $150 pare of so call high technology pedals with chrom-molly axels just shear off right at the crank? These guys are just less than a year old. Have nearly 5,000 miles on them. They were attached to my Lemond Maillot Jaune. Not any more. Ain't going to trust life and limb to those pedals any more. Does anyone know if there is any history here? What would make this happen? OK Boys and Girls I was going to say here's the photos, and I just discovered I don't know how to post an effing photo here. I'll try to figure it out. Ed |

Right at the threads? or where the shaft transitions in size - and had no radius? No radius at a transition WILL cause a stress rizer - where it will eventually break. Too tight is unlikely to cause a fracture at this stage of the game - too LOOSE is more likely- because when tight there are no "load-unload" cycles - no flexing. Flexing causes failure moreso than tension. ** Posted from http://www.teranews.com ** |

Actually somewhat difficult to apply excessive torque. Factory install manual recommends 40 nm, roughly 354 inch-pounds. http://www.unitconversion.org/energy...onversion.html Bill That's 30 ft lbs of torque on a roughly 1/2" national fine thread. No where NEAR enough to damage a high strength shaft. And difficult to overtorque by much with an 8mm allen key. I'd be more inclined to suspect it was LOOSE than too tight. ** Posted from http://www.teranews.com ** |

Sheared off pedal - How's that happen?
Getting an idea of where you’re at legally is difficult: search word/ term ? Try http://www.google.com/search?hl=en&r...&btnG=S earch 2 pages in And: product liability If there’s a court hose down the street try the Westlaw computer online database in the law library. Westlaw has all the answers but again search terms and using the database may be difficult, at first. Westlaw offers an English word search option. My guess is ‘product liability’ in Westlaw offers a long annotated essay in the area. You need to find an expert who does metallurgy or science product liability and have the expert handle an inspection by his experts. Online advert for some. They write an inspection report as an affidavit, the offending company’s legal staff will know your experts, and then you demand compensation for your damages: medical bills, loss of mobility, pain and suffering, possibly punitive damages if the manufacturer’s quality control missed a serious flaw. Upfront then, the manufacturer is guilty or not guilty then you argue about how much money guilty My opinion is a 9/16th’s shaft waved in front of a jury isnot likely to go unnoticed. |

Searching "products liability" in Westlaw would give you a bazillion hits. Just find a reputable lawyer and be prepared to give up a quarter to half your recovery, depending on the fee agreement. This is an easy, easy case, and the only thing HazeRider has to worry about is looking credible -- and injured. He could handle the case himself, but, like plumbing, it is time consuming if you do not know what you are doing. I wouldn't bother getting an expert report until first attempting to get the case settled. I have defended a lot of broken parts cases, and unless the failure arguably resulted from some negligence on the part of the rider (crashing the pedal hard, whacking it with a sledge hammer, using it to break up concrete, etc.), the exact cause of the failure is not important -- except from an R&D standpoint (and Look will want the pedal and a confidentiality agreement as part of any settlement. That's SOP). The important point is that the pedal broke JRA within a year after purchase -- and the break caused the crash. IMO, the argument is going to be over the extent of damages. Always remember that jurors generally hate cyclists unless they are cute or particularly deserving. Otherwise, they are crazy risk-takers and obstacles to motorists (jurors). HazeRider would be better off settling -- unless he is cute and adorable or in a wheelchair. -- Jay Beattie. |

Does anyone know if there is any history here? What would make this happen? Seriously consider legal advice. Make no more statements to anybody Oh, hell, he can talk to anyone he wants -- even us. It doesn't matter unless he confesses to beating the pedal with a sledge hammer. I mean the sucker broke within a years after it was purchased. Even a baby lawyer could squeeze some money out of this case. Pedals should last longer than 5K miles -- they better because I have the same Keo model on my bike with about the same mileage. Tick, tick, tick. In fact, I was riding on a Keo this weekend -- just one, though, because my other pedal is a $10 rattrap that I can use with the boot on my healing broken leg. I look forward to seeing the pictures. I don't think the spindle has a dramatically reduced cross section around the main bearings and don't think it is just too whimpy for us pedal mashers -- at least I hope not. A CroMo pedal that light is a little suspicious, though. -- Jay Beattie. Thanks, Jay. I erred on the side of caution. -- Michael Press |
