The Triple triangle was meant to equal a stiffer rear end, but is really more of a USP / marketing point to differentiate them from everyone else.
For what's desirable, road or MTB, they really don't have a road heritage, it's MTB. or BMX where they started.
For Ti, there was the Xixang which was their premium made in USA Ti MTB frame, with the Lighting which was the made in Taiwan version, both these were pre Pacific & Doral days. The Zaskar is their high end alu MTB, with the Psyclone the high end chromo, however the Zasker name is now applied to a lot of their line up now.
Someone else more knowledgeable can give some info on their road range, but their current range only spec's up to 105 bikes, which are nothing special.
