My BV is a SM.* The effective TT is darn near the same as the Racer X and my old Litespeed Unicoi. Oh yeah, and exactly what Tom Kellogg spec'd on my Spectrum.

I did buy it for exactly the reason so many people initially screamed. A longer than norm TT vs traditional mixte geometry, which I hate. No power position, and your butt and spine take a beating.

*Why did this just remind me that she has no name yet?
