It seemed you had got it in your bonnet that I'd misled you, which I had not. From memory, you wrote that you paid around 40 euros, and I thought this to be at their maximum worth. A little excessive, but what you gonna do, make your own? I wouldn't consider them as a collector's item, simply something that worked and will go on working until the bike's crushed by a road roller. No I didn't change-my-mind over this and I'm glad you are enjoying the pedals. I doubt they will prove to be the weak link. You remember right, Trevor. And you are right, I don't even remember what I paid, I'm just happy to have pedals whose outer edge don't dig into the lateral middle of my foot, and that work so smoothly that I'd forgotten they were there until you noticed them in that photograph. Thanks for good advice. Andre Jute |

Thanks for good advice. Andre Jute I noticed your comment on the cattle, here's another little reminder from Genesis in Taverner's bible. "Only the flesh with his lyfe, which is his bloud, see that ye eate not." "For verely the bloud of you wherin your lyves are, will I requi Even the hande of all beastes will I require it, and of the hande of man, and of the hande of every mans brother, will I require the lyfe of man: so that he which sheddeth man's bloud, shall have his bloude shed by man agayne : so : God made man after his owne lyknesse. Se that ye encrease, and ware, and be occupped upon the earthe, and multiplye therin." I'm coming round to the thinking that this is not "don't eat meat that has not been drained of it's blood" but "don't eat the flesh of animals". It seems to be that I may eat animal fat and organ meat without injury but the flesh (AKA meat in modern parlance), whether or not it is Kosher, Halal or aged well, exhausts me. That "it drains my blood" seems particularly apt. If you think of it, muscles need blood and this may apply whether utilising muscles in life or consuming them AS meat in death. They will draw blood whether in use or through digestion. Simples. It'd take a lot of deception to cover that one up. It is becoming clearer that the natural lifespan of man is 120 years if he does not eat the flesh of animals. This is as declared in Genesis. We must eradicate the animal flesh from our bodies, as is sucks our bloud, our lyfe away. Only by a diet rich in fruits, fats and greens may we counter the injury which continues to cause weakness and illness. A feeble mind - feeble body. Be persuaded to give away your life to the tricksters, doctors and scientists or live by the instruction manual our creator has left. God gave us all that moves, that we may eat, but for the flesh of animals. Taking the flesh of an animal, may as well be your brother, for you will pay with your life. My eyes have been diverted from the truth for too long. For too long I have been deceived . I have take back control of MY thoughts and doings and shall not return to be directed by any man (or woman) howsoever their robes glisten or their voice booms. You have your answer within yourself. See that ye knows it and not receive direction from man. |

There's a difference between a valid concern and saying that it's the wrong material for the job. I'm glad that they recall parts when there is a concern, even if it's just a fear of lawsuits or loss of sales. |

Anyway, other people don't seem to care. This morning, I passed some woman wearing sandals and riding a Roubaix. WTF? There's also a lot of CF sales generated by bike clubs where there is significant peer pressure to be on CF. But the most ridiculous thing is the trend toward carbon fiber forks on aluminum or steel framed bicycles. Why would someone choose to have the only carbon fiber piece of a bicycle be something that is so prone to failure and where the failures often result in bad things happening? https://www.google.com/search?q=carbon+fiber+fork+recall&oq=carbon+fiber+ fork+recall&aqs=chrome.0.57j62l3.6501j0&sourceid=c hrome&ie=UTF-8 Because steel forks are like a boat anchor by comparison. 100,000km on my previous steel frame with the same carbon forks (Giant blades with Al steerer) through it's life. When I rebuilt it for a mate, I put on some new forks - but not "uber light stuff", more like "over engineered but still heaps lighter than steel" forks. My new steel bike has CFRP forks with Al steerer. Eastern EC70. They've done 2-3 years already and seem to be just fine, and much lighter than a steel fork. http://www.wiggle.co.uk/easton-ec70-carbon-road-forks/ (I didn't look very hard) http://www.wiggle.co.uk/surly-steamr...ck-bike-forks/ Note that there is little tyre clearance on the EC70 fork, but I have no intention of using a wider tyre on the front. EC70 about half the weight in 1.1/8" I don't fuss /too/ much about weight - heck I race a steel frame and deep Al rims. But I don't see the point in lugging extra kgs around for the heck of it. $60 extra? $60 is nothing in the grand scheme. Most of the marketing I see for CF forks is about smoothing the ride rather than lowering the weight. Specialized Secteur is AL frame with CF fork, chain stays and seat post. I test drove one when last shopping for bikes and it felt good. I usually don't like AL. Don't know if it was the CF bits. At any rate, the Secteur was a size too small and there was a last year's model full CF Tarmac that was about the right price. I took that out for 50k. It was about the same price as the Secteur and the rest is history. This will probably start another flame war. I've owned bikes with carbon fiber forks and all steel bikes and frankly I've never found that the carbon fiber forks soaked up any more shocks than the steel forks. And, I once bought an expensive carbon fiber seat post and frankly couldn't see any improvement in the ride. I think the comparison is usually CF against AL. From my experience my CroMoly bike was the most comfortable. The CF bike comes in second and the AL bikes sucked. But this is a sample of 4 and highly subjective. |

Seriously, we're looking at cases where 2 out of 12000 cracked and the company issued a recall. The way product recalls work is that the company determines that there's a problem based on a relatively small number of reported problems. Not everyone reports a failure. 2 out of 12,000 may like a small number of failures, but it was indicative of a manufacturing or design problem. Only if the manufacturer's investigation determines that there's an actual defect that caused the failure do they issue a recall. Sometimes component manufacturers get into disputes with bicycle manufacturers over the need for a recall, i.e. see http://www.cervelo.com/en/support/recalls.html and scroll down to the "Wolf SL Fork Recall" (it's the third recall down, just under the recall for the R2.5 carbon fiber frame recall). |

I think that is very much true today. Probably due to the over abundance of Lawyers :-) But years ago if the whatchmacallit broke on your new car you took it back to the dealer and he fixed it. Now the car companies are terrified of a class action suit and have a recall. As an aside, I've always been amazed at some of the judgments the courts seem to make. "Lawyer's Lips" for example. Said to be a protection against the wheel falling off if one neglects to tighten the axle holding device. Is there no concept in law that one should not operate something unless one actually knows how to do it? It's not judges deciding that lawyer's lips are necessary -- it's juries, although the judge does decide what instructions will be given. Anyway, an attorney somewhere convinced a jury that a bicycle was defective because it did not have lawyer's lips. Defective means that it was more dangerous than expected by an "ordinary consumer." Or the allegation could have been that the manufacturer was negligent for failing to have lawyer's lips or some other wheel retention device. The defendant in that case undoubtedly argued that the plaintiff was a schmo who should have checked the quick release. The jury said, "well, maybe yes, but . . . " There may have been a big comparative fault allocation to the plaintiff but still a net verdict in his or her favor. Many states have "pure comparative fault" where a plaintiff can recover even though he or she is 99% at fault. The damages are just reduced by 99% in that scenario. -- Jay Beattie. |

I think the juries were right in this case if the standard was "the ordinary consumer." For all the whining about "lawyer lips" they don't really affect anyone other than racers who either have custom forks or file off the lawyer lips. |
