- Cyclists comparing bike models or frame sizes
- Worth noticing
- The homepage lists 159 models and 1,040 frame sizes across 11 brands, with geometry identified by model year.
Field notes
The homepage names Compare, Size finder, Explore, and All bikes as entry points, and describes comparing two frames through an overlaid drawing. It says the catalog covers road, gravel, and mountain bikes, with manufacturer geometry organized by model year. Stack, reach, and head angle are among the dimensions it calls out; the extracted page does not expose the full comparison or sizing workflow.
