Cinelli King Zydeco Geometry: Read Stack and Reach by Generation
Cinelli King Zydeco geometry is more informative when the generation stays attached to each measurement. In the 2025 catalogue, Medium King II has 563 mm stack and 388 mm reach; original King Medium has 550 mm stack and 380 mm reach. Sharing a letter size does not make their frame coordinates identical.
Cinelli King Zydeco geometry uses two different Medium rows
The II Medium's 140 mm head tube sits alongside a 1,032 mm wheelbase. The original Medium lists a 130 mm head tube and 1,018 mm wheelbase. These measurements belong to their respective complete rows. Copying a reach figure from one and a head-tube figure from the other would create a bicycle that neither table describes.
Some numbers are shared: both Medium rows give a 71.5-degree head angle and 430 mm chainstay. That agreement does not erase the differences elsewhere. A component or fitting enquiry should include the generation even when one familiar dimension matches.
Read the progression, not just the middle size
King II XS begins at 531 mm stack and 362 mm reach, while XL reaches 600 mm stack and 408 mm reach. Medium sits between them at 563 and 388 mm. Keeping both coordinates in the comparison is more useful than treating the difference as a single larger-or-smaller verdict.
The original's table shows fork rake as 47/52 mm, whereas the II rows list 52 mm. This is a documented distinction, not a recommendation to alter a fork or change a dropout setting. The original's named fork versions also differ by build, so an isolated rake number cannot identify the equipment on a particular bicycle.
Use the chart to frame a specific fit enquiry
The catalogue listing is Cinelli KING ZYDECO 2 - GRX 2X12 Bike — DIRTY BLUES. Ask which geometry document accompanies the selected configuration before using the older 2025 table to make a purchase decision. Colour and option labels establish identity clues, not a complete measurement certificate.
Bring a confirmed current bicycle's measurements and intended riding position to a fitting discussion. This table supplies neither a tested handling comparison nor a universal height range. The brand introduction provides context; the Cinelli collection links the separate equipment questions.
Geometry FAQ
Do the Medium stack figures match?
No. The documented King II is 563 mm; the original Medium is 550 mm.
Does a shared head angle mean identical geometry?
No. Head-tube length, wheelbase, stack and reach still differ between the cited Medium rows.
Can the chart predict how either bicycle feels?
It supplies dimensional references, without a field test or a rider-specific handling assessment.
