I actually have been researching this. Due to a request from a guy on RBR and due to my own attitude about CF for ATBs.

1 - you can find 'cheap' Ti frames in China - but I do not bring frames from China. Those frames cost about the same as a Carbon Fiber Frame.

2 - there is one super good Ti maker in Taiwan. I would say the same quality as Litespeed. However, their frames are twice the cost of a good CF frame.

3 - on direct purchases it is easy to get customers a super nice monocoque carbon frame for $399 -- but for the quality I would demand on Ti the price would be more like $799

I am still thinking of this for FLY cross-country mountain bikes; but mainly due to my beleif that falling on a rock with an ATB frame should not make you wonder if you will have a total frame failure in the next mile.
I maybe testing this idea at Sea Otter

Anyway, if enough people agreed on a quality Ti frame; I can make that happen as long as Taiwan is OK with everyone. I am not ready for China [or it is not ready for me, depending on your point of view]
