Just came across this... sounds interesting to say the least, but you won't catch me spending $1,100 on a rod.

$1150 USD
This dude sounds plum off his rocker, you can get Ti rods for the CR500 shipped clear from Germany for $450. And that's even a whole shit ton of money to spend on a rod...
He needs to seriously post up some pics (not that it would make $1100 look good). But I think maybe that post is supposed to be a joke?? Haha

What about not running a bearing? That sounds a litle scary to me.

Exactly!! Titanium is softer than steel. Anytime you have metal to metal contact on parts you do not obviously want to use soft alloys. Ti axles need to be hardened and coated to last 3/4 the life of a steel axle, and cost 3-4 times more on top of it. I understand he says they're coated with something but still, some things are better left made out of steel IMO...

Hardness. Titanium is a much harder metal than aluminum and approaches the high hardness possessed by some of the heat-treated alloy steels. Iodide purity titanium has a hardness of 90 VHN (Vickers), unalloyed commercial titanium has a hardness of about 160 VHN and when alloyed and heat-treated, titanium can attain hardnesses in the range of 250 to 500 VHN. A typical commercial alloy of 130,000 psi yield strength might be expected to have a hardness of about 320 VHN or 34 Rockwell C.

i think you read that wrong it appears that is 1400 per rod...if you notice the price goes down as the number of rods go up.
