|The Vulcan looks kick ass. Boron Carbide frame is warrenteed for life, as opposed of most which is 5 years.|

|... only that it was on my short list before I bought the P2K...
They're popular among triathletes (dunno 'bout their road frames) but, I'm thinking that their tubing is not true aero (though it has an aero profile) and they ain't cheap (which is why it fell off my list... a complete P2K for the cost of a Vulcan frame).
My P2K is only 2 years old... and sees relatively light duty... but I suspect that the frame has more than five years in it (knock on alloy).
Still, the Vulcan has it's proponents and merits. So many bikes... so little money.

|The shop I work at is a Griffen...or was. We have given them the boot for quality control. Nice looking bikes, true. But their attention to detail is very poor. Of the four I built, The hole for the rear brake was drilled out so far off you couldn't get the brake pads low enough on a Dura Ace brake to not contact the tire when braking. That is very poor quality control. Other things include threads full of paint and head tubes needing facing before build becuase so much paint is on it. This is not what I would expect from a premier small frame company. If I am not mistaken, they aren't even making frames anymore. Something happened internally with the family and the company has broken up.|
|Thanks, but aluminum has low fatigue life, No?||Mauceri|

|The reason why I'm thinking Griffen over Cervelo is that Aluminum has a low fatifue life....that is why most aluminum bike frame makers like cervelo only warrenty the frame for 5 years.
The Griffen, due to it being made out of Boron Carbide is Lifetime warrenty to the original owner.
That's why the hesitation with cervelo, felt or giant. Thanks.

|I do have several other aluminium rigs (Cannondales and a GT) which are holding up quite well.
Aluminium has a limited fatigue life and elasticity, meaning that once it's deformed, it retains said shape... and is structurally weakened, however, most builders in the material "overbuild" their frames to compensate for said. As an alloy, aluminium is a major component of an airliner that sees far more duty cycles than a bicycle yet remain airworthy for years. I wouldn't be concerned about fatigue per se... but repair of damage (so don't crash)... that's the downfall of an aluminium frame... it's generally not cost effective to repair a severe deformation (ala steel or titanium). OTOH, most aluminium frames can take a fair amount of dings (just keep an eye on them for signs of "growth"). I have no qualms about buying an aluminium frame from a reputable builder (just got a new Klein frame... yet to be built and a very low milage GT which should outlast me).
Oh, and I still see old P2's out and about, still huffing along (they go back to '96 I believe).
