But on most bikes, those modern reach numbers are paired with a fairly steep seat tube angle because if you lengthen the front of the bike and don't steepen the seat tube, then you end up with a super long top tube and a weird, very stretched out riding position while seated. Which looks to be exactly what's going on with the Canyon - long reach, slack seat tube, and super long top tube measurements. Compared to a bike like the Blur, in any given size the Lux is moderately longer in reach (about 10mm longer), but waaaay longer in the top tube (about 35mm longer).
Also worth noting that, even with progressive geometries, top tube measurements haven't changed all that much over the last decade. The distance from saddle to stem that makes for comfortable seated riding isn't any different now than it was then. Even the most progressive bikes with ridiculously long reach numbers have shorter top tubes than that Lux.
