Nice to see the Onza Ti Dave. I never saw these in the metal, and even wondered if they were just marketing/ tradeshow hype.
Any chance of a few more pics. They really do seem to be rough forged, with the smallest amount of machining. Very cool.

+1 I always assumed that these never made it past prototype stage....

The cranks aren't mine, I just borrowed the pictures from Merlin boy:

Seeking crank fetishist's identification please! These came on my 1996 Marin Team Titanium, bought second hand in '99. The previous owner thought they were Middleburns but I'm pretty sure they're not. They don't look like Cook Bros or CQP, the nearest I could find...

But the reason for my distress:

...yes, the left-hand crank has cracked. I very much doubt much can be done to help it, but as they're beautiful cranks I'd like to find out if it's repairable, or to find a replacement!

I'd appreciate any information you knowledgeable bunch can offer.

I'm pretty sure those are Topline cranks. I had one a couple of years ago. You can go here to look at a synopsis:

Fab - thanks Mr. Gibson! So I'm guessing that a lone LH 175mm crank will be quite hard to come by...

Off to post something in the classifieds ntl...

is the morati cranks the only ones out of titanium or are there other ones that you guys know about?

There are several but here are some pictures of the onza crank and Propeller.

thanks for the reply david. Hopefully now I can indulge some more in my titanium fetish
i really cant imagine the onza ones crack as easy as the morati... but the other ones hmmm....

Well, Onza Ti cranks are not forged. They were cast. Only the prototypes were machined from a billet (Greg Herbold should own one of them). Unfortunately, they got lots of micro cranks when the the casting mold was removed. Micro cracks are no good. Some failed on the first ride. This is why they were never produced for the masses. Even Moratis should be more durable.
Another picture of Onza cranks is in my gallery.

It's great to see you posting again deralex, long overdue!

Do you, or anyone else happen to know the identity of this lovely Ti crankset featured on 24pouces beautiful Passoni? :
