It probably requires plenty of snake oil to prevent squeaks! ;-) If those round stays are flexing as much as they claim, that would be one SCARY bike to ride, IMHO. I can't imagine mounting V-brakes on a seat stay that could flex enough to move the dropout (axle) "several mm's". It'd be like riding a bucking broco. It might be fun to go to a retailer and ask 'em if you could see what it feels like to flex the dropouts up 3mm though. They might get suspicious when you show up with a hydraulic press to do it though. Mark Hickey Habanero Cycles http://www.habcycles.com Home of the $795 ti frame |

What's the big deal? Ibis, Merlin, and many others have all used
flexing chainstays for suspension in the past. I thought it was going to be *good* optical illusion, like this one: http://forum.bikemag.com/photopost/d...l_illusion.JPG -Mike |

I can't imagine mounting V-brakes on a seat stay that could flex enough to move the dropout (axle) "several mm's". It'd be like riding a bucking broco. Given your experience with manufacturers, I am surprised you have never observed flex testing of frames and forks. If you can get a chance, unlikely as it may be, LOOK has a fork testing apparatus. It holds the pivot at the crown, and the legs are bent backwards up to a centimeter, for hundreds of thousands of cycles. Décathlon tours its stores with the frame flex machine, which twists, akternately, the head tube and the rear triangle, for as much as a centimeter (so I recall), for hundreds of thousands of cycles. It might be fun to go to a retailer and ask 'em if you could see what it feels like to flex the dropouts up 3mm though. They might get suspicious when you show up with a hydraulic press to do it though. And that's exactly the kind of test bed they use. Two manufacturers of top pro equipment. It's a shame they don't know what they're doing as well as you do. Maybe you could write to them and advise .... -- Sandy The above is guaranteed 100% free of sarcasm, denigration, snotty remarks, indifference, platitudes, fuming demands that "you do the math", conceited visions of a better world on wheels according to [insert NAME here]. |

Rather than post bland disclaimers about oddly constructed sentences, try asking a straight forward question without gratuitous adjectives. The web page was not reasonably edited for English "flat-sping" or for technical accuracy. The "rear triangle" of the bicycle frame shown is like those of most conventional frames in that it is a tetrahedron, the most rigid structural space frame imaginable, supporting only tension and compression. For this reason these tubes can be as slender as they are in classic steel frames. The forces haven't changed, only the frame materials have. The flexing forces indicated in the web page are imaginary as are the text contentions. Jobst Brandt |

There was no disclaimer - you must still have difficulty reading. Also forgiven. And you don't know the answer, anyway. You haven't given it any thought. They have. But don't let that disturb your view of the world as it used to be and won't ever be again. Why not ask Merida what they mean - perhaps they would answer your less than arrogant questions. -- Les faits relatés ici ne sont que pure fiction, et ne sauraient être utilisés ou rapprochés d'une situation réelle existant ou ayant existée |

The flexing forces indicated in the web page are imaginary as are the text contentions. Looking at the photo, it appears that they may have joined the chainstays to the dropouts with a pivot joint. I suppose they may be expecting that the dropout will thereby be able to couple some force into the seat stay by rotation at the joint. To me, if this has any actual effect at all, it is a bug, not a feature. -- Typoes are a feature, not a bug. Some gardening required to reply via email.
