I own a 56 cm Tetra Pro, std geometry. The website lists the TT as 56 cm. No matter how hard I try to skew it, I only get 55cm (ctr of ST to center of HT). The kicker is that even though I specified a 56 TT, and all my other bikes which fit me have 56cm TT, the Calfee fits perfectly. I've also had the bike for a year and only measured it last week. Never thought to do it before since it fit so well.
I'm curious for those with stock Calfees, does your TT measure as advertised?
Maybe I'll e-mail Calfee to see their take.

Your top tube should measure correctly when you measure horizontally to the top of the seat collar, not along the slightly sloping top tube.

You might be getting a "perfect" fit due to slight seat setback too. It's pretty easy to compensate +/- 1 cm in just about any direction to obtain a perfect fit.

So you are you saying from the top of the collar, mid ST (presuming no extension) and then to the middle of the TT/middle of the HT juncture?
That seems a little contrived but I'll check it.

Yup. Calfee has a slightly sloping top tube, so he states his seat tube measurment as from the cent of BB to the bottom of the binder where a 'virtual' horizontal top tube would intersect the seat tube.
