That much is true Gridds, but there are VERY few frames, even top dollar mainstream ones that havent had problems, or been snapped/broken by the companies team or test riders.

That's a fact.

frame failures of current generation frames (i.e. not a 5 year old bike) are a result of bad design engineering or manufacturing problems...and that's all i am saying on this subject  Tongue

thats why new frames are covered by a warranty covering manufacturing defects.

and why most times DH bikes crack, they get replaced under warranty, because its a result of a dodgy weld, or a known weak spot in a frame, or something not being heat treated properly.

Its happened for years, and it will always happen.

no brand is immune to it.

or at least, if any brands are immune to it......... they are over built Wink  and not a DH race bike.

Right. So let me get this straight. Sorry to divert from the Yeti 303 issue.. but..

An Empire cast frame has snapped, under intended use, within a year or so?

An Empire cast frame, that utilised the best technology "used in the motor cycle industry", that has had extensive R&D, including full FEA by the supposed 'best in the business', has even been redesigned to a certain extent and was even overbuilt so it wouldn't fail, has failed?

The whole principle behind the frame was to eliminate weak points (e.g. welds) where other frames are weak. Was it not?

Yet now it does something that some people said would happen (who were apparently, to quote Dirt - "talking out of their arses") and snaps in half 'like a poppadom'.

Oh dear. That is embarrassing.

Yeah he does.

Most frames wil crack, depending on useage and conjditions.

Even Specialized f**ked up the demo in 05, an had to sort it out.

Aslong as it's only a monir break, an you don't snap your neck it's no big deal, you het a shiny replacement Smiley

Obviously they should be up to there intended perpose, but this world has bigger issues, but that's another subject.

makes me laugh this as nothing was mentioned when marc beaumont snapped a chainstay in italy at the worlds .......


i think you will find that the axle came out so the wheel was running against the frame , which twisted the back end.

ah cool was watching it on freecaster but never heard anything of it until now cheers for clearing that up as my mates interested in one Cheesy

FEA, computer modeling and all that shitnaz does  very well at telling you where weak spots are going to be and whatnot, but it still relies on a monkey to input the right loads... Not imputting the right loads results in snappy snappy.
Computers are great but they are not perfect, even formula one teams test thier products for real after the computer has, because problems ALLWAYS arrise from real life testing. Thats what team riders are for, to find out what the computer didnt.
That empire swingarm was a proto, so not the final jobbie. no doubt they have looked at it and made it better.
I really dont like your attitude in that post, fair enough getting some facts straight, but when what you are ranting about is bent you just look like a complete tool
