The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The L drawn to scale from the table, with no build on it. Stack and reach run from the bottom bracket to the top of the head tube; every size is solved from those two. One square is 100 mm. A dashed tube is a number the maker left out (est.).
The maker's cockpit
No stock cockpit I can name, so every size is solved on a generic stem and bar unless you choose one on the sheet.Generic stem and barAssumedNo bar is listed for this frame.

Notes on the source
SECOND-HAND NUMBERS: copied from Bike Insights (https://bikeinsights.com/bikes/649d4fb8098336001bb28183-wilier-triestina-cento1air?version=2020&build=base), not read off the maker's own table. Source: aggregator (Bike Insights)
How I read Bike Insights' table
Bike Insights cites the maker's page: https://wilier.com/en/my2020/int/racing-bikes/road-bikes/cento1air. The maker no longer publishes this table, so these numbers have not been checked against it; the seed stores this version as an aggregator source and caps its band (D17, D4 second amendment). Build: Base. Bike Insights files it as Road Bike / Paved Road Bike / Performance Road. Where it measures differently: top_tube_effective is its effective_top_tube_length_center_center. Trail is left null: Bike Insights computes its own and the maker's is not on the page. Not checked against the maker's archived page: web.archive.org blocked this machine on 22 Oct 2026; a later pass should read the capture and upgrade this file to the maker's numbers. Close to the Cento10 SL table (wilier-cento10-sl.json) but not the same: half-millimetre stacks and reaches on several sizes, top tubes and head tubes 1 mm apart and shorter chainstays on the L to XXL, so it is kept as its own table.
