Cinelli King Zydeco Tyre Clearance: Keep 45C, 47C and 650B Separate
Cinelli King Zydeco tyre clearance changes between the two generations in the 2025 catalogue. King II is listed up to 700×45C. The original King has separate 700×47C and 27.5×2.1-inch entries. A search result quoting the larger figures should not automatically be applied to a II.
Cinelli King Zydeco tyre clearance belongs to its frame record
The II's maximum appears both in its headline specification and detailed frame table. The original's wider-format figures appear under its own model heading, with 650B wording in the specification panel. Keep the wheel format as well as the width when copying either entry.
A maximum-clearance statement is different from the tyre fitted to a listed complete build. It also does not document clearance with a particular mudguard, rim or measured tyre combination. No fender-specific figure or alternative-wheel conversion approval is established by these rows.
Shared wheel names do not describe identical packages
The II GRX 820 two-by column lists Fulcrum Rapid Red 500 wheels and Pirelli Cinturato H 700×40 tyres. The II GRX 610 one-by column instead names WTB ST i23 rims with Shimano hubs and Vittoria Terreno Dry 700×40 tyres. Both tyre entries are narrower than the II's stated maximum, but their wheel descriptions remain different.
The original Apex Eagle build uses Rapid Red 500 650B with Vittoria Barzo 27.5×2.1 tyres. Its Ultegra column uses Rapid Red 500 with Pirelli Cinturato H 700×40. The repeated Rapid Red name cannot erase the 650B qualifier in the first package.
Compare the actual wheels and the applicable limit
The catalogue listing is Cinelli KING ZYDECO 2 - GRX 2X12 Bike — DIRTY BLUES. Confirm its supplied wheel and tyre references rather than assigning the older catalogue's assembly to it by title alone. The local finish differs from the 2025 II examples.
For a proposed tyre change, identify the precise frame, wheel and intended tyre, then obtain the applicable requirements. Neither the family photograph nor a nominal width proves a replacement fits. The Cinelli range introduction and brand collection provide context for this generation-specific comparison.
Tyre and wheel FAQ
Does 47C describe the documented King II maximum?
No. The II table gives 45C; the 47C figure belongs to the original King record.
Is a 700×40 stock tyre a maximum-clearance figure?
No. It identifies a fitted nominal tyre entry, separate from the frame's published limit.
Does Rapid Red 500 establish one wheel diameter?
No. The original Apex column explicitly adds 650B, while other assembly columns have different tyre-format entries.
