Decided this is the year to buy a dedicated tri bike and return the Kestrel 200 back to its intended use. Although I lust for a Tiphoon, the Caliente looks to be the identical geometry and would fit me just about right. Anybody out there riding either one willing to offer their opinion? Are you happy with it? Do the carbon Fiber seat stays on the Caliente do any good? What about the cranks and BB (Truvativ?) Is it worth forking up the extra 1000 for the Tiphoon? Despite all the comments and opinion that materials don't matter as much as construction, I have never ridden an aluminum road bike (just steel and CF) so a bit leary of of the ride.

Also very interested to hear more about the new KM40 that will be introduced at InterBike this fall. Am told it will be available in 700 wheel size and much wider sizing that current offering (thanks to Asian manufacturing). Thanks for any insights you may be able to offer
