According to bikeradar Cancellara's Domane has a 15cm HT, but there's no 15cm HT on a H1 fit Madone.

Edit: Isn't the center to crown of the fork different, too?

It is H1 minus 5mm from the HT.

I appreciate the info you are trying to provide, but this just doesn't make sense. The Domane has the exact same wheelbase as the Madone? Hard to believe.

Then the regular Domane has those hidden fender mounts, but those are missing from the pro bikes. What about this one?

I do like the concept of the Domane, but the geo is extremely relaxed, not only when it comes to fit, but also handling.

I'll head over to my local Trek dealer, I hope they know something.

Also chainstay length and fork span (for clearance) and bb height should be different.

I will make a call to trek and see if I can get some answers. The pro bikes are layed up differently, and do not have replaceable hangers.

So the H1 bikes to be released are not the same as the H1 bikes the pros are using.....
How significant a difference will the UCI allow and still consider that the "commercial availability" regulation is satisfied?

Dropping the BB a cent. effectivly makes the head tube 1 cent. longer from madone.

Just ordered a 2013 H1 fit from my LBS, apparently they made 250 H1 team frames to comply with UCI rules and if you know someone, you can get one.
