Stack and Reach of Trek Madone, Domane

Previously I plotted the Trek Madone stack-reach. Consistent with using "race bikes" from other manufacturers, I used the more aggressive of the two geometries, the H1. The H1 used to be called the "pro" geometry, in contrast to the more relaxed "performance" geometry, but Trek decided, apparently, that this implied the more relaxed geometry was a lower standard, compelling weekend warriors to buy bikes which didn't fit them well. So the "pro" became H1, and the "Performance" became H2.

In addition to the Madone, the Domane is also a legitimate race bike, sold for comfort at some cost in mass. The standard Domane, as is the standard with "endurance" bikes, has relatively relaxed stack. To compel professional riders, most notably Fabian Cancellara, to ride the frame a lower-stack model needed to be developed. Since the UCI requires bikes given to professional riders be made available to the public, Trek made available a "Domane Race" version, with low stack. I must say this looks to be a very attractive bike.

Here's how the stack-reach numbers compare on these frames:

I show for comparison Cervelo geometry, 2008 and 2014.

The Madone H2 is very similar to the H1 with 4 cm of spacers. They also have an additional size in the H2: 8 versus 7 for the H1. This is very impressive. A lot of bike models are sold in only 6 sizes. Cannondale sells 8. The Trek Madone has 15. But even if it's relatively relaxed versus the H1, the H2 is within 1 cm of spacers within the Cervelo R5. So it's hardly endurance category.

The Domane Race is even more aggressive than the Madone H1, which should make Fabian happy. Obviously with Trek selling only one model, at over $10k each for the full bike, the intent isn't widespread distribution on this one.

The Domane is more relaxed still. A Domane with slammed stem is like an H2 with between 2 and 3.5 cm of spacers on the stem, depending on size.

All of the bikes are clearly designed to a stack-reach standard, since the parameters sweep out nice smooth curves in stack-reach space. They're not straight lines, like Cervelo pioneered, but then perhaps straight lines aren't optimal.
