Canyon Grail CFR Di2 vs Specialized Diverge 4 Sport Carbon
Both published charts held against each other, on the specs that decide what the bike carries.
The short answer
The Grail CFR Di2 takes frame bag space; the Diverge 4 Sport Carbon takes tire clearance. Which matters more is your route, not a scoreboard.
Assembled from the differences below rather than written over them, so it cannot drift from the table. Every figure is the manufacturer's; nobody here has ridden either bike.
Where they differ
3 of the 5 things we can compare come out differently. The rest are close enough not to decide anything.
Frame bag space
211 cm² more on the Grail CFR Di2Front-triangle area at the largest size, computed from stack, reach and seat angle. It is what decides how much full-frame bag you can run, and a frame bag is the one place weight sits low and central.
Widest published tire
8mm more on the Diverge 4 Sport Carbon on 700c / 29inThe frame figure, not the fork's — forks are routinely cut for more rubber than the rear triangle, and compared only on a wheel size both frames publish. Loaded, tire width is also seat-pack clearance: a big tire and a sagging pack compete for the same space.
Fork cargo mounts
only the Grail CFR Di2 publishes somewhere to bolt a cageCage mounts on the fork blades. This moves weight low and off the bars, which is where a heavy bar roll does the most to the steering. A frame with none published may still have them — it means the maker does not say.
Side by side
Including the rows where the two are level, because a spec that doesn't separate them is still a spec you might be checking.

Drawn to scale
Largest published size of each, built from the charts rather than illustrated. The front triangle is the part that decides frame bag fit.
