one of these caught my eye recently and i had to have it. it's a titanium lynskey helix. i have only ridden one other titanium bike that i liked, and this one is even better. to be sure that it would be stiff enough, i'm using an alpha Q fork with a cromoly steerer tube.
indeed it is stiff. probably not stiff enough for dan, because he likes to make titanium bike owners cringe by twisting them like a pretzel, but it's pretty darn stiff.
it's also not very expensive. i'm surprised at how many carbon frames costs a grand or more in excess of the helix.
i've only ridden it twice. both have been torturous tuesday night races.
so far, i really like it. and it's shiny.
