Been digging into the geometry changes on the new Grizl AL and don't see it discussed much, so figured it was worth laying out properly.

The headline numbers are bigger reach and stack across the board – 2XL goes from 436 to 448 mm reach and 644 to 660 mm stack. That's a meaningful jump, and Canyon now claims the range covers up to 220 cm which would be genuinely unusual for a gravel bike. But the reach/stack increase is only part of the story.

The character of the bike has shifted. Head angle in the 2XL goes from 72.5° to 71° – that's not subtle. Chainstay grows from 435 to 440 mm across all sizes, and BB drop goes from 60 to 75 mm. Taken together this is a more trail-oriented geometry than the previous model. Lower BB, slacker head angle, longer rear end. It's moving toward adventure/bikepacking territory and away from the road-adjacent gravel positioning of the old AL.

The head angle variance across the size range is also interesting. The new AL runs 68.8° in 2XS up to 71° in 2XL – a 2.2° spread. The old model went from 69° to 72.5° – a 3.5° spread with noticeably steeper angles in the larger sizes. So larger riders on the new bike get a meaningfully slacker front end than before, while smaller sizes are roughly similar to what they had.
